[Linux-cluster] fence_ipmilan issue

In order to get the node back into the cluster, I had to reboot all
the nodes. Not exactly what I want to have happen. Still not sure
why the rgmanager was hung.
Instead of calling fence_ipmilan, decided to see what would happen if
I pulled the ethernet cable to a node running a service. From
/var/log/messages on one node I see the following:

The last 3 lines continue to repeat. Any clues as to what might be
wrong? Here's an updated cluster.conf
