NOAA-EMC/NCEPLIBS-prod_util#73 updates err_exit to make it more robust so that we don't get any issues where err_exit does not kill a slurm job immediately
More details are documented in the following two issues:
NOAA-EMC/NCEPLIBS-prod_util#72
NOAA-EMC/rrfs-workflow#953
Hope this PR may be merged soon and included in the next spack-stack release. Thanks!
