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.
