[Beowulf] MPICH2: Handle Limit?

I've been having some strange problems with a program using the MPICH2
library. When I added some new datatypes for ghost cell exchange, the
program would hang. I figured out that any number of handles over 84
would cause this. Fortunately, I could delete some handles that I no
longer needed, but it still seemed strange. Are my calculations
correct that for each process there is an 84 handle limit? or am I
seeing some other problem?
