Hi,

I have noticed that from time to time, the job queue seems to be “stuck” and can only be unstuck by restarting galaxy.

The jobs seem to be in the queue state and the python job handler processes are hardly ticking over and the cluster is empty.

When I restart, the startup procedure realizes all jobs are in the a “new state” and it then assigns a jobhandler after which the jobs start fine….

Any ideas?

Thon

P.S I am using the june version of galaxy and I DO set limits on my users in job_conf.xml as so: (Maybe it is related? Before it went into dormant mode, this user had started lots of jobs and may have hit the limit, but I assumed this limit was the number of running jobs at one time, right?)
