knl05 went down (panic), and Cobalt kept scheduling jobs on it. Same issue as Steve reported. Don't quite have a fix for this yet. You have access to nodes were scheduled as part of job 548, the next job that comes along will correctly set permissions for the new job. I'll add to my todos to cleanup access after a failed job launch. Thanks, Ben

Hi JLSE support,

I'm not sure if this a known issue or not. I noticed some strange behaviour last night on the cobalt for KNL. My jobs submitted to knl_7210 exited without starting. I also noticed that I can ssh directly to several nodes without being allocated by cobalt for running jobs.

The cobalt log and my job script is attached.
