<P><FONT SIZE=2>Thanks Shaun. That did solve the problem. I typed the ulimit -l unlimited in my window, but when one does the ssh it gets system default value. Having that limit set in sshd resolves that issue. <BR>

Thanks for trying MVAPICH2. Have you tried putting the following in your<BR>
/etc/init.d/sshd files:<BR>
<BR>
ulimit -l unlimited<BR>
<BR>
and then restarting sshd first on both machines? This is noted in<BR>
section 7.2.4 of the MVAPICH2 User Guide:<BR>

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