Hi,
I understand that the simplest explanation for your problems are the security updates. However, we have done the updates on our test clusters and many other systems already, where no such effect occurred. Besides, slurm packages where not part of the update. So I can only assume that some other changes you have made on the cluster caused this and the effect of it was only visible after the reboot. The only option left for you is to debug the issue.
OK, good to know. I had thought it was odd that Slurm would have been affected, so we will now focus on any changes we had made prior to installing the security update.
Thanks!
Dave
