Chad Callihan has a story in three acts:
Once upon a time, I was having a relaxing morning…until I received an e-mail alert about an Error Number 825 on a database. The error stated:
‘D:\sql_dat\DatabaseName.mdf_MSSQL_DBCC47’ at offset 0x00000004b9e000 succeeded after failing 1 time(s) with error: 121(The semaphore timeout period has expired.). Additional messages in the SQL Server error log and system event log may provide more detail. This error condition threatens database integrity and must be corrected. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
That’s not how you want your day to go. Fortunately, the database was not one that needed to be online 24/7 so I felt I could relax a little bit while starting to investigate. At this point, the issue seemed to be with one database.
