Possible Sign That A Database Is Corrupt? I have a database that's size is 100GB.  When I run CHECKDB on it, it fails to due a lack of space for tempdb, which has over 1TB of space.  I can restart my SQL Server, flush out tempdb, the drive has 1TB of available space, and run it again, and it will use everything and fail due to a lack of space.

I suspect the database is corrupt because this seems like odd behavior, but is there a scenario where a 100GB database would use more than 1TB for running CHECKDB?

UPDATE

The table that didn't pass DBCC CHECKTABLE, I recreated its indexes and will see if it verifies faster.
Normally a few events of 823 and 824 are warnings that there is possible corruption on the database, also if you have backups of this database that are failing and or jobs on it that fail to complete.
