A native full backup of msdb on a SQL Server 2005 Enterprise instance (9.0.4053) deployed on a two-node Win2K3 cluster (Microsoft Windows NT 5.2 (3790)) is currently stuck in rollback.

The DB is in Simple recovery mode but the Tlog is full. Attempts to add secondary Tlogs are failing due to a 3023 error (regarding the action needing to be serialized).

Options I'm considering are moving non DB files off the volume to allow for autogrow of the Tlog and instance restart. I've tried changing the state of the DB from multi-user to single-user but the SPID stuck in rollback is blocking. SPID 126 is the session in question below.

Are there other options I can consider?

Even if you restart the instance, it will do a crash recovery and will have to rollback again. what is causing it to hold-up .. run this sql SELECT session_id ,status ,blocking_session_id ,wait_type ,wait_time ,wait_resource ,transaction_id FROM sys.dm_exec_requests WHERE status = N'suspended' – Kin Oct 4 '13 at 20:57

yes, the wait time translates to 20+ days – MattyZDBA Oct 4 '13 at 21:01
that is not proper output. What is blocking the backupthread ? Is this Production server ? – Kin Oct 4 '13 at 21:05
full output added in question area – MattyZDBA Oct 4 '13 at 21:16
