SQL error preventing nightly backups

[WithoutMotive]

Anyone know what this error is in the event log:

 

Event Type: Error

Event Source: SQLVDI

Event Category: None

Event ID: 1

Date: 27/08/2008

Time: 23:01:01

User: N/A

Computer: ADMINSERVER

Description:

SQLVDI: Loc=CVDS::Cleanup. Desc=Release(ClientAliveMutex). ErrorCode=(288)Attempt to release mutex not owned by caller.

. Process=3756. Thread=1080. Client. Instance=SIMS2005. VD=.

 

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

 

Whatever it is, it's happening just before our backups kick in and, therefore, preventing them from completing.

 

Thanks.
