FIX: 1108 Errors with Heavy Tempdb Activity

• Microsoft SQL Server, version 6.5

SYMPTOMS

SQL Servers with lots of tempdb activity, sorts, and deadlocks can get 1108 errors in the error log and at the client. The following error message appears:

   Error : 1108, Severity: 21, State: 1
   Cannot deallocate extent 944, database 2. Object id 0, index id 0,
   status 0 in extent does not match object id -49604, index id 0, status 0
   in object being deallocated.  Run DBCC CHECKALLOC

CAUSE

You can get 1108 errors in tempdb when there are sorts of small work tables and some other event occurs such as a deadlock or cancel, causing a backout. Normally, the client is already backing out for some other reason so they don't even notice the error, but it does show up in the errorlog.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5. This problem has been corrected in U.S. Service Pack 1 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.
