    SchedMD (the maintainers of Slurm) have discovered a critical security flaw in Slurm. Due to the nature and severity of the issue, we will be immediately applying this patch.

    Cannon and FASSE schedulers will remain down for the duration of the patching. All running jobs will be paused, and new jobs will not be accepted until the scheduler is back up.

    ETA is expected to be approximately one hour.
