To temporarily stabilize the situation, we have reduced the maximum query time for sacct and other Slurm commands to be 1 day. We have filed a ticket with SchedMD to further analyze the issue. The cluster is back up and the scheduler is accepting new jobs. We will continue to monitor for emergencies over the weekend, and resume in-depth troubleshooting on Monday.
