SharePoint job queued, but never starts

I'm attempting to retract a solution from SharePoint. I've started the job via Central Admin site as well as from stsadm. The job is queued, however, it will stay in a state of pending for days. The SharePoint services - Admin and Timer service - are started.

Any suggestoins of why the retraction jobs are queued, but never start开发者_Go百科ed? I'm really at a loss of what to try next, so anything will be helpful.

Thank you!

What happens when you run "STSADM -o execadmsvcjobs" from one of the servers on the farm? this should flush the job queue, displaying any errors occurred along the way.

Make sure the SharePoint 2010 Timer service is running.
