On our system this is usually a result of user error. Particularly if
people don't use the environment variable ${SLURM_NTASKS} in their batch
scripts, they may end up requesting a number of cores, but passing a
different number to their MPI launcher for the number of processes to
start.
However, your version of Slurm is quite old, so it is conceivable that
you are being bitten by a probably long-fixed bug.
Cheers,
Loris
