I'm having a problem with an EXCEPTION_ACCESS_VIOLATION.
Running SQL 2000 (SP3) and connecting using an OleDb.OleDbConnection in the vb.net client application.
This error only seems to occur when I'm hitting the server with loads of updates/inserts (sqlCommand.ExecuteNonQuery) - it doesn't happen at the same place or with the same record. The routines in question are ones that run through a list of records, do some calculations, and then update a different table with a couple of columns.
Once this error has happend on the client (it also happens when the app is run on the server itself), the server more often than not blue-screens (but not always!).
