I'm having a problem where I see consistency errors in my databases on a regular basis (at least twice a week).
I have several databases running on the same instance of SQL Server. During any given week, at least one of the databases will show consistency errors. At times, more than one at the same time will show these errors. These have odd effects on queries, sometimes making a SELECT (for instance) that should run in 5 seconds have to be killed after running for over an hour.
I'm running SQL Server 2000, version 8.00.194. The host OS is Windows 2000 with the latest service pack. RAID 5 is the storage solution.
Below are two DBCC outputs from different databases on the same machine. They are slightly different in that one starts out with "Parent node for page was not encountered"; and the other with "Page is missing a reference from previous page".
My hardware guys assure me there is no hardware failure going. I don't see anything that would suggest there is one in any of the event logs or in the Dell OpenManage system checks.
These DBCC errors are repairable without data loss, yet the databases have to be taken down to single user mode to do so (unacceptable during the day). But at the same time, certain operations in the database become impossible to perform when these errors crop up (such as the aforementioned infinite SELECT problem).
Any help in diagnosing why these pop up, or how to prevent them would be greatly appreciated.
The DBCC outputs:
