Believe this is now fixed with r21582 - let me know if it now works for you.
Sorry for the problem. It was indeed miscounting the number of daemons in the system, though apparently this wasn't causing problems for slurm and torque (still investigating why since it should have). Unfortunately, just changing the index caused shared memory to think everyone was remote, so the fix was a tad more involved - though not particularly difficult.
