Sql-server – SQL Server 2008 unable to backup due to Failed to flush the commit table to disk in dbid 11 due to error 2601

sql serversql-server-2008

I tried to backup the SQL Server 2008 database
using the following code: 

BACKUP DATABASE [DataStore] TO  DISK ='E:\SQLServerDatabase\DataBasebackUpOct302012.bak'

and I get the following error:

Msg 2601, Level 14, State 1, Procedure sp_flush_commit_table, Line 15
Cannot insert duplicate key row in object 'sys.syscommittab' with
unique index 'si_xdes_id'.

Msg 3013, Level 16, State 1, Line 1 BACKUP DATABASE is terminating
abnormally. The statement has been terminated.

Msg 3999, Level 17, State 1, Line 1 Failed to flush the commit table
to disk in dbid 11 due to error 2601. Check the errorlog for more
information.

Could somebody suggest a solution to this problem?

The version is Microsoft SQL Server 2008 (RTM) – 10.0.1600.22 (X64) Jul 9 2008 14:17:44 (64-bit) on Windows NT 6.1 (Build 7600: )

Aaron Bertrand,
Thank you. I am going to look into service packs and hope that is going to resolve the issue.

SQL-Learner,

Never used the change tracking services before.But we had unexpected Windows Server shutdowns due to mishandling 2-3 times.

Looks like I have to apply a service pack.

mrdenny,

Results after using DBCC CHECKDB
Errors:

Update 11/9/2012
I applied the Service Pack3 to SQL Server 2008 but I still could not create the back of the database. I have not rebooted the server as it didn't ask for it.
Will have to reboot and check if the patch applied.

Would appreciate any comments/ideas as to how to go about it.
Thanks.

Do you happen to use the change tracking services provided by in SQL 2008 Enterprise? If so, it's time to update your system. Please try to avoid running RTM anywhere. It's very risky from a security and sometimes stability point of view. :)
