Bug #: 470503 (SQL Server 8.0)



SYMPTOMS
If many unused query execution plans that are generated for queries against temporary tables remain in the SQL Server procedure cache, the computer that is running Microsoft SQL Server 2000 may experience performance degredation. The query execution plans may remain in the SQL Server procedure cache even after the associated temporary tables are out of scope and are dropped from the tempdb database.
