It's safe to restart MOMs with single-node jobs, but restarting MOMs
with multi-node jobs is still unstable.

That requires building a new pbs_server database and can't be done while
jobs are queued or running.

qmgr -c 'p s' > /tmp/pbs_server.conf
kill pbs_server
pbs_server -t create
qmgr < /tmp/pbs_server.conf
