That looks similar to the problem I posted recently, running on a 
4-way parallel SGI machine, but with PVM_ARCH = SGIMP.  The out-of-space
message did deal with semaphores, not disk space.  Try "ipcs -sa" to 
query the active semaphores.  My problem was fixed by version 3.3.10.
Perhaps you should give that a try.

Have fun,
