[slurm-users] Why every job will sleep 100000000

[GHui]

I found a sleep process running by root, when I submit a job. And it sleep 100000000 seconds.
Sometimes, my job is hung up. The job state is "R". Though it runs nothing, the jobscript like the following,
----------
#!/bin/bash
#SBATCH -J sub
#SBATCH -N 1
#SBATCH -n 1
#SBATCH -p vpartition

----------

Is it because of "sleep 100000000" process? Or how could I debug it?

Any help will be appreciated.
