FIX: Error Message 1203 Followed by Stack Overflow With Keyset Cursors (272426)
The information in this article applies to:
- Microsoft SQL Server 6.5 Service Pack 2 and later
This article was previously published under Q272426 BUG #: 18833(SQLBUG_65) SYMPTOMS When the FETCH process of a keyset cursor is blocked by
another user transaction during lock escalation and is then subsequently
released from blocking, the following 1203 error message occurs:
Caller of lock manager is incorrectly trying to unlock
an unlocked object. spid=%d locktype=%d dbid=%d lockid=%Id The error
message may be followed by "stack overflow" error messages in the errorlog and
sometimes the SQL Server server becomes unresponsive. CAUSE When the FETCH process completes, it tries to release the
locks that are no longer held due to lock escalation. WORKAROUND Change to a different cursor type (for example, Dynamic).
STATUS Microsoft has confirmed this to be a problem in SQL Server
version 6.5. This problem has been corrected in the Post Service Pack 5a Update
