<P><FONT face=Arial size=2>Help! :)</FONT> </P>
<P><FONT face=Arial size=2>We've been seeing a problem where most of our nodes
drop out of the MPICH2 ring; this has happened three times in the last two
days. It's not always the same nodes, either :(</FONT></P>
<P><FONT face=Arial size=2>The syslog file on our head node shows the
following error:</FONT> </P>
<P><FONT face=Arial size=2>(handle_rhs_challenge_response 1010): INVALID msg
for rhs response msg=:{}: from host=xxxxx</FONT> </P>
<P><FONT face=Arial size=2>xxxxx represents the various hosts which drop out
of the ring.</FONT> </P>
<P><FONT face=Arial size=2>Could this be a misbehaving job?</FONT> </P>
<P><FONT face=Arial size=2>Help! :)</FONT> </P>
<P><FONT face=Arial size=2>I'm using mpich2-1.0.1 on RHEL3</FONT> </P>
