This is quite unusual. Do you run the prolog as root by intention? I assume so
to set the limits:
$ qconf -sq my.q
…prolog /some/script
Do you have here "root:" to change the user (in the global `qconf -sconf`)
under which it is run? Please note that this my open some root doors, depending
on environment variable setting. I have here "sgeadmin:" for some special
handling and use:
sgeadmin@/usr/sge/cluster/busybox env -u LD_LIBRARY_PATH -u LD_PRELOAD -u IFS
/usr/sge/cluster/context.sh
Nevertheless: the second approach to get the additional group ID from the job's
spool area should work.
