Thanks for trying MVAPICH2. Have you tried putting the following in your
/etc/init.d/sshd files:

ulimit -l unlimited

and then restarting sshd first on both machines? This is noted in
section 7.2.4 of the MVAPICH2 User Guide:

http://nowlab.cse.ohio-state.edu/projects/mpi-iba/index.html

We've found this necessary, in addition to modifying
/etc/security/limits.conf.
