Unless you've set Direct Routing, the message is going to get buffered
in pvmd both at the sending and receiving machines.  So you're 2.4MB is
going through 3 separate socket connections, two of which are on the
same machine.  If you're short on memory, I would suspect that you are
in fact thrashing the memory as pvmd and your application try to share
the machine.
