Hmm, you might well be right, I might have done that work before we switched 
to Slurm on x86 (2013 - we always ran Slurm on BG/P and BG/Q).  So yes, it 
could have been because we saw that issue on Torque instead and I assumed it 
would do the same on Slurm.

Still, even in a threaded mode it would end up with threads blocked in the 
dreaded 'D' state if the health-check scripts end up blocking wouldn't it?

Nice to hear NHC can work around that!

All the best,
