Problem with job & database

I have a problem with Galaxy which we're running locally. Somehow we overloaded Galaxy with the jobs which resulted in the database server going down. Now when I try to restart Galaxy the following error is displayed:

galaxy.jobs DEBUG 2010-02-08 17:14:08,705 recovering job 1050 in local runner
