Hello everyone.

I have a cluster composed of 16 nodes, with 4 of them having GPUs with no particular configuration to manage them.

The filesystem is gluster, authentication via slapd/munge.

My problem is that very frequently, let's say at least a job daily, gets stuck in CG. I have no idea why this happens. Manually killing the slurmstep process releases the node but this is in no way a manageable solution. Has anyone experienced this (and fixed it?)

Thank you.
