SYMPTOMS

The Microsoft ASP.NET worker process stops responding, or "hangs," and when you use a debugger such as the Windbg debugger to examine a user dump that was taken at the moment that the process stopped responding, many of the threads appear to be waiting on a critical section as shown in the following stack:
ChildEBP RetAddr  Args to Child

The thread that owns the critical section has the following stack:

This thread is waiting for all the threads to suspend work to start the GC but it hangs there forever (until the process recycles)
A thread exists that has not enabled garbage collection and it has the following stack:
ChildEBP RetAddr  Args to Child              
165bf7ac 77ebb04d d0000144 00000004 00000000 ntdll!ZwRaiseHardError+0xb

165bffec 00000000 79200971 00000000 00000000 kernel32!BaseThreadStart+0x65
The exception stack trace looks like the following:
ChildEBP RetAddr  Args to Child              
165bfea4 791c333a ffffffff 165bff6c 792f395b mscorsvr!ArrayList::GetPtr+0xf

165bff84 792009dd 00000000 00000000 16ba3fa0 mscorsvr!BindIoCompletionCallbackStub+0x13 
165bffb4 77e887dd 00000000 00000003 00000000 mscorsvr!ThreadpoolMgr::CompletionPortThreadStart+0x93 
165bffec 00000000 79200971 00000000 00000000 kernel32!BaseThreadStart+0x52
The ASP.NET worker process stops responding because the completion port receives a corrupted overlapped structure.
