Chuck writes "Backup software invokes DBCC CHECKDB on every SQL Server 7 database before it backs it up. Backups are done every night. Every night but one, DBCC CHECKDB runs quickly. One night a week, DBCC CHECKDB runs 3 times as long. Any ideas as to why it takes 3 times longer one day a week (it runs slow on the same day every week)?

Thanks,

Chuck"
