Hi all,
I had a slurm partition gpu_gmx with the following configuration (Slurm version: 20.11.9):
> NodeName=node[09-11] Gres=gpu:rtx4080:1 Sockets=1 CoresPerSocket=8 ThreadsPerCore=1 RealMemory=62000 State=UNKNOWN
> NodeName=node[12-14] Gres=gpu:rtx4070ti:1 Sockets=1 CoresPerSocket=8 ThreadsPerCore=1 RealMemory=62000 State=UNKNOWN
> PartitionName=gpu_gmx Nodes=node[09-14] Default=NO MaxTime=UNLIMITED State=UP
A job running on node11 had a problem, which then triggered the reboot of all nodes (node[09-14]) within the same partition (cat /var/log/slurmctld.log):

The operating systems are CentOS 7.9.2009 on master node, and CentOS 8.5.2111 on node[09-14]. Does anyone have a similar experience and have a clue how to resolve this?
Thanks in advance.
Best,
