FIX: Merge Replication Reconciler Stack Overflow

View products that this article applies to.

SUMMARY

When you run the SQL Server 2000 merge replication ActiveX control in an application that has a default thread stack size that is less than 1 megabyte (MB), an EXCEPTION_STACK_OVERFLOW exception may occur.

Under a user-mode debugger, the call stack for the thread that is experiencing the exception will look similar to this:

 # ChildEBP RetAddr  
00 0442f7b0 03030c94 REPLPROV!_chkstk+0x17
01 0442fe5c 10046aec REPLPROV!CMergeDatasource::CommitBatch+0x1a4
02 0442feb4 10047103 replrec!CDatabaseReconciler::ProcTombstonesMTDest+0x44c
03 0442ff3c 1004466c replrec!CDatabaseReconciler::DestThreadProcessQueue+0x3d3
04 0442ff80 1020c323 replrec!DestThreadProc+0x12c
05 0442ffb4 77e8b2d8 MSVCRTD!_threadstartex+0x73
06 0442ffec 00000000 KERNEL32!BaseThreadStart+0x52

You can use the Dumpbin.exe utility (with the /HEADERS option) to determine your application's default thread stack size. The "Stack Reserve" value in the output is the size of the space reserved for a thread's stack.

CAUSE

The merge replication provider DLL, Replprov.dll, allocates space on the stack for storing replication metadata during processing. For applications whose thread stack size is too small to handle this stack allocation, an EXCEPTION_STACK_OVERFLOW is generated when the reconciler tries to make this allocation.
