If you are using LDAP or some other remote name service for username and groups lookup, chances are that the underlying libc library functions are triggering the SIGPIPE. You can likely work around this problem by setting CacheGroups=1 in your slurm.conf file. However, be aware that you will need to run “scontrol reconfigure ” any time your groups database is updated.
