    A number of jobs appear to have terminated during the upgrade for some reason. Those jobs will re-queue or, if not, will need to be re-submitted,
    We apologize for the inconvenience.

    We have been manually dealing with a Slurm memory leak bug behind the scenes and now have an official fix in the form of a Slurm upgrade (26.05.3). It is necessary to get this update in place as soon as possible.

    At 2pm today we will pause the cluster. Jobs will be paused, not terminated, and the scheduler will be unavailable for querying or submitting new jobs until the update is completed. Once complete, jobs will resume.
