SQL 2008 R2 - Failed to flush the commit table to disk

Other errors
Failed to flush the commit table to disk in dbid 10 due to error 2601
Failed to flush the commit table to disk in dbid 8 due to error 8630

Solution 1 (does absolutely nothing):
This issue is resolved in the latest service pack

http://support.microsoft.com/kb/2527041

If the service pack does not resolve the issue, you must repair your SQL installation
Launch SQL Install>Maintenance>Repair


Solution 2 (this one worked for me):
Run a

DBCC CHECKDB (two) WITH NO_INFOMSGS, ALL_ERRORMSGS

then most likely a

ALTER DATABASE two SET SINGLE_USER
GO
DBCC CHECKDB (two,repair_rebuild)
GO
ALTER two SET MULTI_USER
GO

Solution 3 (others have reported this, i tried it, it did not work):
