We could ssh OK. But did find pfilter.conf problems. Made some changes and
restarted pfilter. OK now.
Thanks VERY much!!

That's fairly odd. :-)
It seems like this might be a networking problem -- the "topology" phase
is where LAM is sending around the connection information.
- Did the firewall software somehow get enabled on any of the nodes?
In OSCAR, pfilter *should* be configured to allow connections from any
port to any port within the cluster.
- Can you ssh between all the nodes properly (without a password)?
