Assume that you query the tempdb.sys.allocation_units table in Microsoft SQL Server 2012. When you use NOLOCK hint in the query or the query is under the READ UNCOMMITED transaction isolation level, you receive the following intermittent 608 error message:

Error: 608 Severity: 16 State: 1 No catalog entry found for partition <ID> in database <Database Name>. The metadata is inconsistent. Run DBCC CHECKDB to check for a metadata corruption

Note The DBCC CHECKDB command does not show any sign of database corruption.


The issue occurs because of a dirty read on stale metadata.
