| 4000 | Thread that is exiting owns a critical section. |
| 4001 | Thread ID of the thread that is exiting while owning a critical section. |
| 4002 | Critical section address. Run !cs -s <address> to get more information. |
| 4003 | Critical section debug information address. |
| 4004 | Critical section initialization stack trace. Run dps <address> to dump the stack trace. |
| 4006 | This stop is generated if a thread (thread ID is parameter1) is terminated, suspended or is in a state (worker thread finished a work item) in which it cannot hold a critical section. The current thread is the culprit. To debug this stop use the following debugger commands: $ kb - to get the current stack trace. If the current thread is the owner of the critical section it is probably calling ExitThread. The current thread should have released the critical section before exiting. If the current thread is calling TerminateThread or SuspendThread then it should not do this for a thread holding a critical section. $ !cs -s parameter2 - dump information about this critical section. $ ln parameter2 - to show symbols near the address of the critical section. This should help identify the leaked critical section. $ dps parameter4 - to dump the stack trace for this critical section initialization. |
| 4010 | Unloading DLL containing an active critical section. |
| 4011 | Critical section address. Run !cs -s <address> to get more information. |
| 4012 | Critical section initialization stack trace. Run dps <address> to dump the stack trace. |
| 4013 | DLL name address. |
| 4014 | DLL base address. |
| 4016 | This stop is generated if a DLL has a global variable containing a critical section and the DLL is unloaded but the critical section has not been deleted. To debug this stop use the following debugger commands: $ du parameter3 - to dump the name of the culprit DLL. $ .reload dllname or .reload dllname = parameter4 - to reload the symbols for that DLL. $ !cs -s parameter1 - dump information about this critical section. $ ln parameter1 - to show symbols near the address of the critical section. This should help identify the leaked critical section. $ dps parameter2 - to dump the stack trace for this critical section initialization. |
| 4020 | Freeing heap block containing an active critical section. |
| 4021 | Critical section address. Run !cs -s <address> to get more information. |
| 4022 | Critical section initialization stack trace. Run dps <address> to dump the stack trace. |
| 4023 | Heap block address. |
| 4024 | Heap block size. |
| 4026 | This stop is generated if a heap allocation contains a critical section, the allocation is freed and the critical section has not been deleted. To debug this stop use the following debugger commands: $ !cs -s parameter1 - dump information about this critical section. $ ln parameter1 - to show symbols near the address of the critical section. This should help identify the leaked critical section. $ dps parameter2 - to dump the stack trace for this critical section initialization. $ parameter3 and parameter4 might help understand where this heap block was allocated (the size of the allocation is probably significant). |
| 4030 | Double initialized or corrupted critical section. |
| 4031 | Critical section address. Run !cs -s <address> to get more information. |
| 4032 | Address of the debug information structure found in the active list. |
| 4033 | First initialization stack trace. Run dps <address> to dump the stack trace. |
| 4034 | Second initialization stack trace. Run dps <address> to dump the stack trace. |
| 4036 | Usually this stop is generated if a critical section has been initialized more than one time. In this case parameter3 and parameter4 are the stack trace addresses for two of these initializations. Some other times it is possible to get this stop if the critical section or its debug information structure has been corrupted. In this second case it is possible that parameter3 and parameter4 are invalid and useless. To debug this stop: $ !cs -s -d parameter2 - dump information about this critical section. $ ln parameter1 - to show symbols near the address of the critical section. This might help identify the critical section if this is a global variable. $ dps parameter3 and dps parameter4 - to identify the two code paths for initializing this critical section. |
| 4040 | Free memory containing an active critical section. |
| 4041 | Critical section address. Run !cs -s <address> to get more information. |
| 4042 | Critical section debug information address. |
| 4043 | Critical section initialization stack trace. Run dps <address> to dump the stack trace. |
| 4044 | Not used. |
| 4046 | This stop is generated if the memory containing a critical section was freed but the critical section has not been deleted using DeleteCriticalSection. To debug this stop use the following debugger commands: $ !cs -s -d parameter2 - dump information about this critical section. $ dps parameter3 - to identify the code path for initializing this critical section. In most cases the lock verifier detects immediately leaked critical sections contained in a heap allocation, a DLL range, a virtual memory allocation or a MapViewOfFile mapped memory range and issues different stops in these cases. So there are very few cases left for this verifier stop. The lock must be in a memory range freed by kernel-mode code or freed cross-process by APIs like VirtualFreeEx. Most typically this stop will be encountered if a previous stop (e.g. LOCK_IN_FREED_HEAP or LOCK_IN_UNLOADED_DLL) was continued by hitting `g' in the debugger console. |
| 4050 | Corrupted critical section. |
| 4051 | Critical section address. Run !cs -s <address> to get more information. |
| 4052 | Invalid debug information address of this critical section. |
| 4053 | Address of the debug information found in the active list. |
| 4054 | Initialization stack trace. Run dps <address> to dump the stack trace. |
| 4056 | This stop is generated if the DebugInfo field of the critical section is pointing freed memory. Usually another valid DebugInfo structure is found in the active critical section list. Without corruption the two pointers should be identical. To debug this stop use the following debugger commands: $ !cs -s -d parameter3 - dump information about this critical section based on the current contents of the debug info structure found in the active list (this structure is rarely corrupted so usually this information is trustworthy). $ !cs -s parameter1 - dump information about this critical section based on the current contents of the critical section structure (the structure is corrupted already so sometimes this information is NOT trustworthy). $ dps parameter4 - to identify the code path for initializing this critical section. Dump the critical section at address parameter1 and look for the corruption pattern. With good symbols for ntdll.dl you can use the following commands: $ dt ntdll!_RTL_CRITICAL_SECTION LOCK_ADDRESS $ dt ntdll!_RTL_CRITICAL_SECTION_DEBUG DEBUG_ADDRESS |
| 4060 | Invalid critical section owner thread. |
| 4061 | Critical section address. Run !cs -s <address> to get more information. |
| 4062 | Owning thread. |
| 4063 | Expected owning thread. |
| 4064 | Critical section debug info address. |
| 4066 | This stop is generated if the owner thread ID is invalid in the current context. For example, the critical section is being released by a thread other than the one that acquired it. To debug this stop: $ !cs -s parameter1 - dump information about this critical section. $ ln parameter1 - to show symbols near the address of the critical section. This should help identify the critical section. |
| 4070 | Invalid critical section recursion count. |
| 4071 | Critical section address. Run !cs -s <address> to get more information. |
| 4072 | Recursion count. |
| 4073 | Expected recursion count. |
| 4074 | Critical section debug info address. |
| 4076 | This stop is generated if the recursion count field of the critical section structure is invalid in the current context. To debug this stop: $ !cs -s parameter1 - dump information about this critical section. $ ln parameter1 - to show symbols near the address of the critical section. This should help identify the critical section. |
| 4080 | Deleting critical section with invalid lock count. |
| 4081 | Critical section address. Run !cs -s <address> to get more information. |
| 4082 | Lock count. |
| 4083 | Expected lock count. |
| 4084 | Owning thread. |
| 4086 | This stop is generated if a critical section is owned by a thread if it is deleted or if the critical section is uninitialized. To debug this stop: $ !cs -s parameter1 - dump information about this critical section. If the owning thread is 0 the critical section has not been initialized. $ ln parameter1 - to show symbols near the address of the critical section. This should help identify the critical section. |
| 4090 | Critical section over-released or corrupted. |
| 4091 | Critical section address. Run !cs -s <address> to get more information. |
| 4092 | Lock count. |
| 4093 | Expected lock count. |
| 4094 | Critical section debug info address. |
| 4096 | This stop is generated if a critical section is released more times than the current thread acquired it. To debug this stop: $ !cs -s parameter1 - dump information about this critical section. $ !cs -s -d parameter4 - dump information about this critical section. $ ln parameter1 - to show symbols near the address of the critical section. This should help identify the critical section. |
| 4100 | Critical section not initialized. |
| 4101 | Critical section address. Run !cs -s <address> to get more information. |
| 4102 | Critical section debug info address. |
| 4103 | Not used. |
| 4104 | Not used. |
| 4106 | This stop is generated if a critical section is used without being initialized or after it has been deleted. To debug this stop: $ ln parameter1 - to show symbols near the address of the critical section. This should help identify the critical section. |
| 4110 | Critical section is already initialized. |
| 4111 | Critical section address. Run !cs -s <address> to get more information. |
| 4112 | Critical section debug info address. |
| 4113 | First initialization stack trace. Use dps to dump it if non-NULL. |
| 4114 | Not used. |
| 4116 | This stop is generated if a critical section is reinitialized by the current thread. To debug this stop: $ !cs -s parameter1 or !cs -s -d parameter2 - dump information about this critical section. $ ln parameter1 - to show symbols near the address of the critical section. This might help identify the critical section if this is a global variable. $ dps parameter3 - to identify the code path for the first initialization of this critical section. $ kb - to display the current stack trace, that is reinitializing this critical section. |
| 4120 | Freeing virtual memory containing an active critical section. |
| 4121 | Critical section address. Run !cs -s <address> to get more information. |
| 4122 | Critical section initialization stack trace. Use dps to dump it if non-NULL. |
| 4123 | Memory block address. |
| 4124 | Memory block size. |
| 4126 | This stop is generated if the current thread is calling VirtualFree on a memory block that contains an active critical section. The application should call DeleteCriticalSection on this critical section before if frees this memory. $ kb - to display the current stack trace, that is calling VirtualFree. The probable culprit is the DLL that calls VirtualFree. $ !cs -s parameter1 - dump information about this critical section. $ dps parameter2 - to identify the code path for the initialization of this critical section. |
| 4130 | Unmapping memory region containing an active critical section. |
| 4131 | Critical section address. Run !cs -s <address> to get more information. |
| 4132 | Critical section initialization stack trace. Use dps to dump it if non-NULL. |
| 4133 | Memory block address. |
| 4134 | Memory block size. |
| 4136 | This stop is generated if the current thread is calling UnmapViewOfFile on a memory block that contains an active critical section. The application should call DeleteCriticalSection on this critical section before if unmaps this memory. $ kb - to display the current stack trace, that is calling UnmapViewOfFile . The probable culprit is the DLL that calls UnmapViewOfFile. $ !cs -s parameter1 - dump information about this critical section. $ dps parameter2 - to identify the code path for the initialization of this critical section. |
| 4140 | Current thread does not own any critical sections. |
| 4141 | Critical section address. Run !cs -s <address> to get more information. |
| 4142 | Number of critical sections owned by current thread. |
| 4143 | Not used |
| 4144 | Not used |
| 4146 | This stop is generated if the current thread is calling LeaveCriticalSection but, according to the internal verifier bookkeeping, it doesn't own any critical section. If parameter2 is zero, probably this is a bug in the current thread. It either tries to leave a critical section that it didn't enter, or maybe it is calling LeaveCriticalSection more times than it called EnterCriticalSection for the same critical section. If parameter2 is not zero (it is a negative integer number) the internal verifier data structures are probably corrupted. |
| 4150 | Using critical section that is private to another DLL. |
| 4151 | Critical section address. Run !cs -s <address> to get more information. |
| 4152 | Not used. |
| 4153 | Not used |
| 4154 | Not used |
| 4156 | This stop is generated if the current thread tries to use a private lock that lives inside another DLL. For example a.dll tries to enter a critical section defined inside ntdll.dll. Private locks cannot be used across DLLs. |
| 4500 | The SRW Lock is not initialized. |
| 4501 | SRW Lock |
| 4502 | Not used |
| 4503 | Not used |
| 4504 | Not used |
| 4506 | This stop is generated if a thread is trying to use the SRW lock (Param1) that is not initialized. $ kb - to get the current stack trace. This is where the SRW lock is being used. The SRW lock should be initialized using InitializeSRWLock before it can be used. |
| 4510 | The SRW Lock is already initialized. |
| 4511 | SRW Lock |
| 4512 | ThreadId of the thread that initialized the SRW lock. |
| 4513 | Address of the initialization stack trace. Use dps <address> to see where the SRW lock was initialized. |
| 4514 | Not used |
| 4516 | This stop is generated if the SRW lock (Param1) is being re-initialized. If the SRW lock is being actively used by other threads, re-initializing the lock will result in unpredictable behavior by the application including hangs and crashes. The initialization stack trace may show an acquire if the SRW lock was statically initialized. $ kb - to get the current stack trace. This is where the SRW lock is being re-initialized. $ dps Param3 - to get the SRW lock initialization stack trace. This stack trace may show an acquire if the lock was statically initialized. |
| 4520 | Mismatched Acquire-Release on the SRW lock. |
| 4521 | SRW Lock |
| 4522 | ThreadId of the thread that acquired the SRW lock. |
| 4523 | Address of the acquire stack trace. Use dps <address> to see where the SRW lock was acquired. |
| 4524 | Not used |
| 4526 | This stop is generated if the SRW lock (Param1) is being released with a wrong release API. If the SRW lock was acquired for shared access and is being released using the exclusive release API or the SRW lock was acquired for exclusive access and is being release using the shared release API. This can result in unpredictable behavior by the application including hangs and crashes. $ kb - to get the current stack trace. This is where the SRW lock is being released using the wrong API. $ dps Param3 - to get the SRW lock acquire stack trace. |
| 4530 | The SRW lock is being acquired recursively by the same thread. |
| 4531 | SRW Lock |
| 4532 | Address of the first acquire stack trace. Use dps <address> to see where the SRW lock was acquired. |
| 4533 | Not used |
| 4534 | Not used |
| 4536 | This stop is generated if the SRW lock (Param1) is being acquired recursively by the same thread. This will result in a deadlock and the thread would block indefinitely. Recursive acquisition of an SRW lock in exclusive mode will cause a deadlock. Recursive acquisition of an SRW lock in shared mode will cause a deadlock when there is a thread waiting for exclusive access. Consider the example below: - Thread A acquires the SRW lock in shared mode - Thread B tries to acquire the SRW lock in exclusive mode and waits - Thread A tries to acquire the SRW lock in shared mode recursively. This will be successful as long as there is no exclusive waiter (in this case B). Since SRW locks do not have writer starvation, thread A waits behind thread B. Now, Thread B is waiting for Thread A which is inturn waiting for Thread B causing a circular wait and hence a deadlock. $ kb - to get the current stack trace. This is where the SRW lock is being acquired recursively. $ dps Param2 - to get the stack trace for the first acquire. |

| 4546 | This stop is generated if the thread (Param2) that owns the SRW lock (Param1) is exiting or being terminated. This will result in an orphaned SRW lock and the threads trying to acquire this lock would block indefinitely. $ kb - to get the current stack trace. This is where the thread is exiting or is being terminated. $ dps Param3 - to get the SRW lock acquire stack trace. |

| 4556 | This stop is generated if the SRW lock (Param1) is being released by the thread (Param2) that didn't acquire the lock. This represents bad programming practice that is hard to get right and can lead to unpredictable behavior by the application. $ kb - to get the current stack trace. This is where the thread is releasing the SRW lock that it didn't acquire. $ dps Param4 - to get the SRW lock acquire stack trace. |

| 5004 | Not used. |
| 5006 | This stop is generated if the function on the top of the stack passed an invalid handle to system routines. Usually a simple kb command will reveal what is the value of the handle passed (must be one of the parameters - usually the first one). If the value is null then this is clearly wrong. If the value looks ok you need to use !htrace debugger extension to get a history of operations pertaining to this handle value. In most cases it must be that the handle value is used after being closed. |

| 5014 | Not used. |
| 5016 | This stop is generated if the function on the top of the stack passed an invalid TLS index to TLS system routines. Usually a simple kb command will reveal what is wrong. The typical bug here is to assume a certain value for a TLS index instead of calling TlsAlloc. This can happen either by thinking that you always get value N therefore there is no need to call TlsAlloc or more frequently due to an uninitialized variable. |

| 5043 | Not used. |
| 5044 | Not used. |
| 5046 | This stop is generated if the current thread is currently running code inside the DllMain function of one of the DLLs loaded in the current process and it calls WaitForSingleObject or WaitForMultipleObjects to wait on a thread handle in the same process. This would most likely lead to a deadlock because the thread handle will not get signaled unless that second thread is exiting. When the second thread will call ExitThread it will try to acquire the DLL loader lock then call DllMain (DLL_THREAD_DETACH) for all DLLs in the current process. But the loader lock is owned by the first thread (the one that is waiting on the thread handle) so the two threads will deadlock. |

| 5053 | Expected object type name. Use du to display it |
| 5054 | Not used. |
| 5056 | This stop is generated if the current thread is calling an API with a handle to an object with an incorrect object type. E.g. calling SetEvent with a semaphore handle as parameter will generate this stop. To debug this stop: $ kb - to display the current stack trace. The culprit is probably the DLL that is calling into verifier.dll; $ du parameter2 - to display the actual type of the handle. The handle value is parameter1. In the example above, this will display: Semaphore. $ du parameter3 - to display the object type expected by the API. In the example above, this name will be: Event. $ !htrace parameter1 might be helpful because it will display the stack trace for the recent open/close operations on this handle. |

| 6004 | DLL base address. |
| 6006 | This stop is generated if a DLL that allocated a TLS index is being unloaded before freeing that TLS index. To debug this stop: $ du parameter3 - display the name of the culprit DLL; $ .reload xxx.dll=parameter4 - reload symbols for the culprit DLL (if needed). xxx.dll is the name of the DLL displayed in the above step; $ u parameter2 - disassemble the code that allocated the TLS. This should point to the function that allocated the TLS but forgot to free it before the DLL was unloaded. |

| 7006 | This stop is generated if the app verifier detects a VirtualFree or a DLL unload with an invalid start address or size of the memory allocation. In the case of DLL unload this probably means a memory corruption inside the loaded DLL list. To debug this stop look at the current stack trace and the memory address and size that is about to be freed and try to determine why they are invalid. |

| 7036 | This stop is generated if the app verifier detects an IsBadXXXPtr call with an invalid address (e.g. a kernel-mode address, instead of a normal user-mode address) for the memory buffer to be probed. To debug this stop look at the current stack trace (kb) and try to determine why the caller of the IsBadXXXPtr function ended up with an invalid address. Many times, the address is plain bogus, e.g. an uninitialized pointer. MSDN library lists a few reasons why applications should not use the IsBadXXXPtr APIs: In a preemptive multitasking environment, it is possible for some other thread to change the process's access to the memory being tested. Dereferencing potentially invalid pointers can disable stack expansion in other threads. A thread exhausting its stack, when stack expansion has been disabled, results in the immediate termination of the parent process, with no pop-up error window or diagnostic information. Threads in a process are expected to cooperate in such a way that one will not free memory that the other needs. Use of this function does not negate the need to do this. If this is not done, the application may fail in an unpredictable manner. Because of all these reasons, we recommend to never use these APIs. |
| 7040 | Probing free memory. |

| 7042 | Memory block size. |
| 7043 | Address of free memory page. |
| 7044 | Not used. |
| 7046 | This stop is generated if the app verifier detects an IsBadXXXPtr call for a memory allocation that is free. This is very bad because it is possible that, in some other cases, this memory was already reused for some other allocation. Since the current code path (kb) doesn't own that memory, it could end up corrupting someone else's memory, with disastrous effects. To debug this stop look at the current stack trace (kb) and try to determine why the caller of the IsBadXXXPtr function ended up probing free memory. The address could be plain bogus (e.g. uninitialized pointer) or maybe already freed memory. If the memory was already freed by one of the VirtualFree or UnmapViewOfFile APIs, `!avrf -vs -a parameter3' will search for a log of stack traces of the code paths that allocated/freed that address and display these stack traces if they are available. This might show the stack trace that freed up this memory. More often, the memory is an already freed heap allocation. To check for that possibility, `!avrf -hp -a parameter3' will search for a log of stack traces of the code paths that allocated/freed that address from/to the heap and display these stack traces if they are available. MSDN library lists a few reasons why applications should not use the IsBadXXXPtr APIs: In a preemptive multitasking environment, it is possible for some other thread to change the process's access to the memory being tested.

| 7053 | Address of guard page. |
| 7054 | Not used. |
| 7056 | This stop is generated if the app verifier detects an IsBadXXXPtr call for a memory allocation that contains at least one GUARD_PAGE. This is very bad because it is very possible that this GUARD_PAGE is the end of the current stack of a thread. As documented in the MSDN library: Dereferencing potentially invalid pointers can disable stack expansion in other threads. A thread exhausting its stack, when stack expansion has been disabled, results in the immediate termination of the parent process, with no pop-up error window or diagnostic information.

| 7066 | This stop is generated if the app verifier detects an IsBadXXXPtr call with a NULL address. To debug this stop look at the current stack trace (kb) and try to determine why the caller of the IsBadXXXPtr function ended up with the NULL address. This is typically the sign of someone not checking the return value of one of the memory allocation functions. For example the code below is incorrect: int main (void) { PVOID p; p = malloc (1024); Use (p); return 0; } void Use (PVOID p) { if (IsBadReadPtr (p)) { return; } // // p is safe to be used here. // } This code should be re-written as this: int main (void) { PVOID p; p = malloc (1024); if (NULL == p)) { return -1; } Use (p); return 0; } void Use (PVOID p) { // // p is safe to be used here. // } MSDN library lists a few reasons why applications should not use the IsBadXXXPtr APIs: In a preemptive multitasking environment, it is possible for some other thread to change the process's access to the memory being tested.

| 7104 | Not used. |
| 7106 | This stop is generated if the app verifier detects a VirtualFree with an incorrect value for the FreeType parameter. The only two acceptable values for this parameter are MEM_DECOMMIT and MEM_RELEASE. If VirtualFree is called with any other value except these two, VirtualFree will fail to free the memory. To debug this stop look at the current stack trace (kb): the caller of VirtualFree is probably the culprit. |

| 7134 | Verifier dll descriptor |
| 7136 | This stop is generated if a DLL's entry point (DllMain) function is raising an exception. One example why this is bad is: if DllMain(DLL_PROCESS_ATTACH) is raising an exception, the Windows DLL loader will: - Catch and hide the exception; - Unload the DLL without calling its DllMain(DLL_PROCESS_DETACH). So in many cases the DLL allocated some resources already, then it raised the exception, and it will not have a chance to release these resources on DllMain (DLL_PROCESS_DETACH). To debug this stop: $ du parameter1 - to display the DLL name; $ .exr parameter2 - to display the exception information; $ .cxr parameter3 followed by kb - to display the exception context information and the stack trace for the time when the exception was raised; $ parameter4 is the address of an internal verifier structure and doesn't have any significance for most of the verifier users. |

| 7146 | This stop is generated if a thread function is raising an exception. This is bad because the whole process will be killed. To debug this stop: $ parameter1 might be significant for the type of exception. E.g. an exception code C0000005 means Access Violation; $ .exr parameter2 - to display the exception information; $ .cxr parameter3 followed by kb - to display the exception context information; |
