Slurm DSE: squeue causes RuntimeException

Apparently squeue fails quite frequently with error messages:

slurm_load_jobs error: Socket timed out on send/recv operation
slurm_load_jobs error: Socket timed out on send/recv operation
slurm_load_jobs error: Socket timed out on send/recv operation
...

Which leads to further warnings:

[17:30:12 <scala-execution-context-global-202: Slurm$> WARN] Slurm `squeue` failed: java.lang.RuntimeException: Nonzero exit value: 1
[17:30:12 <scala-execution-context-global-237: Slurm$> WARN] Slurm `squeue` failed: java.lang.RuntimeException: Nonzero exit value: 1
[17:30:12 <scala-execution-context-global-230: Slurm$> WARN] Slurm `squeue` failed: java.lang.RuntimeException: Nonzero exit value: 1
...

And apparently this crashes the DSE:
