Changing the value of 'job_is_first_task' makes no difference.
In either case, the grid engine appears to start the master
process and one slave process on a node, walks through
'$TMPDIR/machines' starting slaves on the nodes listed there,
then tries and fails to start a second slave on the node
running the master.  At that point the job aborts.  All that's
in the 'messages' file in the spool directory of the master's
node is a message like
