We have the following error:
Error: 823, Severity: 24, State: 7.
Operating system error 'incorrect pageid (expected 1:216; actual 0:477691182)' resulted from attempt to read the following: sort run page (1:216), in file 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\tempdb.mdf', in database with ID 2. Sort is retrying the read.
DESCRIPTION: The operating system returned error stale page (a page read returned a log sequence number (LSN) (47:398:55) that is older than the last one that was written (0:0:0)) to SQL Server during a read at offset 0x00000000290000 in file 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\tempdb.mdf'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
I ran dbcc checkdb on all databases with no errors. Our Server Administrator doesn't see any errors.
Any ideas what else we should look for?
Thanks very much.
