Subject: Problem Running PVM over Myrinet (TCP/IP)

I am trying to run PVM  (3.3.11) over Myrinet (using TCP/IP) on RedHat Linux 
5.0, and the pvmd start code seems to be failing.  The problem is that when I 
try to add a host, the addhost command hangs.  When I turn on debugging, it 
appears the the master pvmd is trying to send a message to the slave pvmd 
(which has been correctly started by rsh and is in a select).  The configure 
message never gets through (after 16 re-tries), and the new slave pvmd 
eventually exits due to a timeout (waiting for master) because it never got 
the config message from the master pvmd. Everything works fine when I use the 
100Mbps Ethernet interfaces.

Has anyone seen a problem like this before?
