this might be a bit of a worry given i am testing the PBS. This it is what might have caused my problems today.
I know there was a job which was to run last night which I stopped after 17 hours.
But this is still running now
this is from the remote PBS server
looking at the time I stopped the Remote Sync I see I posted the problem here 15 minutes later.
I will reboot node DC1 tonight and hope it fixes the issue.
