I am getting the "Out of Memory " error in the /tmp/pvml.501 file for the NAS kernel called Integer Sort.  I am using PVM vs 3.3.6, and am running LINUX on two PCs.  Both PCs have 32 Mb of memory.  Interestingly enough, I only get the error when I try to pvm_send information to a separate machine.  When I have the two processes running on the same machine, it works fine.  I've traced it and it definitely is blowing up on the pvm_send.  It never returns to the process that did the pvm_send for me to check t
he return code.

I've issued the "free" command at the LINUX prompt and it says I have 26,000 Kb unused.  The only difference between the two machines is the one it works on is an IDE hard drive and the other machine that it cannot send to is a SCSI hard drive.  I've run smaller memory programs successfully on both.

any ideas?  What are the rules on memory limitations?
