Index corruption

I'm seeing an error when my server runs the built in job to delete the timer job history. Currently running SQL Server 2008 r2 sp2 with the cumulative update #11. Since the job fail, the data grows and grows. Looking through the data, this is the only timer job that does not complete successfully. So, the data itself isn't really critical to preserve. I'd just like to get the job to run so that the file does not continue to grow. The error from the logs is:

CPerIndexMetaQS :: ErrorAbort - Index corruption

There is a stack dump generated which refers to the stored process dbo.process_DeleteOldTimerJobHistory  @DeleteBeforeDate

@RequestGuid.

Thanks,

Paul
