[slurm-users] Jobs take more time then what they need

[Zohar Roe MLM]

Hello,
Having another strange problem with slurm 17.02.6.
I have a cluster with 250 cpus.
I am sending a testing job that only sleep for 60 seconds.
A lot of the jobs are taking more than 7 or 8 minute until they finish running (I can see them in RUNNING mode for more the 7 minutes).
Is there a reason they take so much time? clearly more time that I would expect (which is 60 seconds or maybe a few second more...).
Thanks,

I am using "sbatch myscripy.sh":

echo "hello"
sleep 60
