BUG #: 236374 (SHILOH_BUGS)



SYMPTOMS
A race condition between Microsoft Distributed Transaction Coordinator (DTC) operations may result in a SQL Server assertion failure similar to the following:

Short Stack Dump 77F97AC6 Module(ntdll+00017AC6) (_RtlUnicodeStringToOemString@12+00000050) 0092569E Module(sqlservr+0052569E) (utassert_fail(enum UTASSERT_TYPE,char const *,char const *,int,char const *,...)+000002E9) 0063FB9D Module(sqlservr+0023FB9D) (CMsqlXact::EnlistDTCXact(unsigned char const *,int,class CAutoRefc &)+00000039) 00693303 Module(sqlservr+00293303) (ResetConnAndDtcXact(class PSS *)+00000149) 00858E77 Module(sqlservr+00458E77) (rm_ods_handler_body(struct srv_proc *)+000000E0) 00858D58 Module(sqlservr+00458D58) (rm_ods_handler(struct srv_proc *)+00000053) 00693E8A Module(sqlservr+00293E8A) (process_commands(struct srv_proc *)+000001AC) 410735D0 Module(UMS+000035D0) (ProcessWorkRequests(class UmsWorkQueue *)+00000264) 4107382C Module(UMS+0000382C) (ThreadStartRoutine(void *)+000000BC) 7800BEA1 Module(MSVCRT+0000BEA1) (_beginthread+000000CE) 77E92CA8 Module(KERNEL32+00012CA8) (_CreateProcessW@40+0000035E) --- SQL Server Assertion: File: <&quot;msqlxact.cpp&quot;>, line=1143 Failed Assertion = 'IS_OFF_SAFE (XACT_MUST_DEFECT_DTC, m_status)'.



CAUSE
This condition occurs when a pooled connection is enlisted in a DTC operation and then leaves the transaction and is enlisted in another transaction before the transaction context can be reset.
