FIX: The Mtxoci.dll module of the MSDTC XA Transaction Manager may leak threads (829159)
The information in this article applies to:
- Microsoft COM+ 1.0, when used with:
- the operating system: Microsoft Windows 2000
SYMPTOMSWhen the ODBC driver closes its connections, the Mtxoci.dll module of the Microsoft Distributed Transaction Coordinator (MSDTC) can leak threads. For example, you may find hundreds of the following threads in the Microsoft SQL Server process:
ChildEBP RetAddr
044ffef0 77e56a15 ntdll!ZwWaitForSingleObject+0xb
044fff18 77e56a3d KERNEL32!WaitForSingleObjectEx+0x71
044fff28 066ba975 KERNEL32!WaitForSingleObject+0xf
044fff48 066c0e5b MTXOCI!COCIConnection::FactotumSink+0x45
044fff68 066c0e21 MTXOCI!CFactotum::ServicingState+0x1b
044fff78 066c070c MTXOCI!CFactotum::ThreadMain+0x21
044fff80 7800a27b MTXOCI!ThreadRoutine+0xc
044fffb4 77e5758a MSVCRT!_threadstart+0x57
044fffec 00000000 KERNEL32!BaseThreadStart+0x52 CAUSEWhen the MSDTC XA Transaction Manager disconnects from the database while active transactions exist, an internal reference countering problem may cause the internal service threads inside the Mtxoci.dll module to remain in service.RESOLUTIONHow to obtain the hotfixThis issue is fixed in the Windows 2000
