</div>
<div>I have set-up slurm to use slurm_db and all was working
fine. However I had to change the slurm.conf to play with user
priority and upon restarting the slurmctl is fails with the
following messages below. It seems that somehow is trying to
use the mysql password as a munge socket? </div>
<div>Any idea how to solve it? </div>
