So, I'm having an intermittent issue with the following dump being plastered in my SQLLog on my SQL 2000 SP4 BUILD 2282 system. This stored procedure is executed QUITE frequently, meaning hundreds of times a minute, but only pops up in the log every 15mins or so. The stored procedure is a 3000 line stored procedure (not mine!) that has over 50 conditionals in it.

Any ideas on what could be triggering this dump? I've done a checkdb on the whole db and done checktables on the tables involved. I even attempted to flush the cached plan, and even tried hadding hints to maxdop 1, and still this occurs.

The following is the dump:

SqlDumpExceptionHandler: Process 289 generated fatal exception c0000005
EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process..

On twitter I asked you if this sproc does anything "special", such as XP calls, full text search, linked server, openquery, xml, etc. Are triggers in play?

Too bad it is intermittent ... can't comment out code sections to isolate the cause.

As @sqlsoldier said, you may need a support ticket to get to the bottom of this one, or at least someone familiar with debug symbols and stack dump analysis of SQL 2000.

Nothing special other than some dynamic sql with exec() and conditional statements, and being 3000 lines long. No linked servers or xp calls.

Can you check all the input buffers from the error log entries to see if there is some common thread amongst the sproc parameters? Maybe a funky character is causing something to go south (like the ` character in 'name`30')? Just grasping at straws here ...

Good thinking. Looking at the dumps, it appears every case has the ` character. If i run the sproc statements in SSMS it doesn't trigger the exception though. So, I'm not quite sure that it's purely that character doing it...

This is grasping at straws, grrr. I would totally rewrite this sproc, but it's 3000 lines long, and full of crazy business logic I don't understand :)
