I reset these values to those in the HOMEWORLD config and it worked 
fine. Perhaps you could point me to a reference as to what these are 
and how they used, so that if I have to change them I can do it 
properly. I have the  NMBCLUSTERS=4096 on a number of my machines and 
they function without a problem.

.. and thank you very much.
