SQL Server 2008R2 DBCC CheckDB never finishing I'm running SQL Server 2008 R2 on Windows server 2008 R2 and up until recently we were having no problems. After windows updates recently (no sql server updates) we cannot run step 1 of our maintenance plan DBCC CHECKDB It does not error out, it just runs indefinitely, longest time so far 36 hours. The DB is only about 500MB so I dont think size is an issue.

I was just wondering if anyone has seen this sort of issue in the past.

Edit:
For what it is worth I also noticed rebuilding index and updating statistics is having the same issue. I have no idea if this helps.

Edit2:
So if if it helps anyone after running SELECT * FROM sys.dm_exec_requests; I'm seeing the wait type CXPACKET on the following tasks: ALTER INDEX, DBCC;
There is a very interesting post on DBCC CHECKDB on SqlPerformance, Minimize impact of checkdb. This will give you several ideas, like testing your backup on another server (therefore offloading the charge), using several options (you can experiment with PHYSICAL_ONLY for example). 

As CHECKDB is making a big use of tempdb, this you check how things are going on for this database? Is it on separate disk?
