[Linux-cluster] Node is randomly fenced

[Schaefer, Micah]

The servers do not run any tasks other than the tasks in the cluster
service group. 

Nodes 3 and 4 are physical servers with a lot of horsepower and nodes 1
and 2 are virtual machines with much less resources available.

I adjusted the token settings and will watch for any change.
