If you examine the process hierarchy, that "sleep 100000000" process if probably the child of a "slurmstepd: [<jobid>.extern]" process. This is a housekeeping step launched for the job by slurmd -- in older Slurm releases it would handle the X11 forwarding, for example. It should have no impact on the other steps of the job.
