[Linux-cluster] Node is randomly fenced

[Schaefer, Micah]

I have a 4 node cluster, running a single service group. I have been
seeing node1 fence node3 while node3 is actively running the service group
at random intervals.

Rgmanager logs show no failures in service checks, and no other logs
provide any useful information. How can I go about finding out why node1
is fencing node3? 

I currently set up the failover domain to be restricted and not include
node3.
