the last version of MPICH from 2005 is 1.2.7p1. For newer
installations I would suggest to look into Open MPI.

Means only the 10 nodes?

With so many time, I would suggest to login to all nodes and check with:
$ ps -e f
(f w/o -) the ditribution and startup of the porcesses. Is it doing
nothing for 40 minutes or running fine until it crashes?
