This article was previously published under Q195543
BUG #: 18131; 17558 (SQLBUG_65)
SYMPTOMS
If a query performing a reformatting strategy is prematurely interrupted by
means of either a query timeout or a cancel request, a runtime error 1108
may be generated in tempdb. The object ID will be a negative number,
indicating that the object is a worktable. The following is message 1108:
Msg 1108: Cannot deallocate extent 3200, database 2. Object id -1440009985, index id 0, status 194 in extent does not match object id object id -2050, index id 1, status 0 in object being deallocated. Run DBCC CHECKALLOC.
WORKAROUND
To work around this problem, analyze showplan for the query and see if any
index changes can be made that will avoid the reformatting step. The
reformatting execution strategy is typically used when no useful indexes
are available for processing the query. Therefore, such index changes will
likely improve overall performance.
