This is definitely a corruption issue. Please run DBCC CHECKDB and post the results to the forum. You should also check your system/application event logs for any hardware-related errors, and make sure you run hardware diagnostics on this server.

I can't let you know what you should do to recover until I see the DBCC output.

Thanks,

I didn't realize we printed a smiley at the end of CHECKDB results - must be a bug. Please start a new thread with these result in.

Thanks
