    Slurm crashed on 4:30p on Friday due to a user running a large sacct query against the Slurm database. This caused the database host to run out of memory and crash the scheduler. To prevent this from reoccurring we are reducing the time range that users are permitted to query at one time to 7 days. Thus if you need to cover a month you would need to query in four 7 day increments.

    We do ask users to be judicious in their querying of the Slurm. Only ask for those fields that you require. Please also ensure any AI agents you have running limit their queries appropriately.

    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.

    The Slurm scheduler is experiencing an error which is impacting jobs. The Cannon cluster will be inaccessible while we troubleshoot.

    We are currently investigating this incident.
