hi,

i'm surprised by that, normally people run out of file descriptors. 
i only know about solaris but there is a limit command, and something
like setrlimit() as c library calls.
you might be able to find something in the following include files
	sys/time.h
	sys/resource.h

i don't thing it's an mpi problem, it sounds like the OS ran out of
process space. do you have a lot of stuff running on that machine.

in solaris there is a file
	/etc/system
where you can set how much memory and file descriptor you can use.
perhaps it's somewhere around there.

i know it's nothing concrete, but it might help getting on the right
track.
