When you run Microsoft BizTalk Server in a heavy-load condition, you may receive an access violation error message. The Dr. Watson log (Drwtsn32.log) may contain an entry that is similar to the following:
Access violation - code c0000005 eax=0506ec00 ebx=00000001 ecx=0369aca0 edx=00000000 esi=000ffe40 edi=00000a24 eip=77f96dd1 esp=1c02fe80 ebp=1c02fe98 iopl=0 nv up ei pl nz na pe nc cs=001b ss=0023 ds=0023 es=0023 fs=0038 gs=0000 efl=00010202 ntdll!RtlDeregisterWaitEx+39: 77f96dd1 8b4008 mov eax,[eax+0x8] ds:0023:0506ec08=????????
This problem may occur if Windows 2000 incorrectly handles the implementation of the thread pool. This can occur in situations where a long period of time exists between when a Wait function is satisfied and when a Deregister function is called. In this case, the Wait thread exits, and the number of Waits that are associated with a particular thread is decremented.
