The information in this article applies to:

Microsoft SQL Server 6.5

This article was previously published under Q179924

BUG #: NT: 17748 (6.5)

SYMPTOMS

If SQL Server receives an attention signal during the maintenance to a table's nonclustered index after an insert operation, message 1203 may be generated. Attention signals are caused by a query timeout expiring, or by using the dbcancel() or SQLCancel() functions within DB-Library or ODBC programs, respectively. The following is message 1203:

Msg 1203 Level 20 State 1
Caller of lock manager is incorrectly trying to unlock an unlocked object. spid=10 locktype=6 dbid=4 lockid=353

WORKAROUND

To work around this problem, increase the query timeout or avoid using cancel functions. Also, if there is only one index and it is a nonclustered index, you can change the index to a clustered index to avoid the problem.
