[ClusterLabs] Fence agent ends up stopped with no clear reason why

[Casey Allen Shobe]

Across our clusters, I see the fence agent stop working, with no apparent reason.  It looks like shown below.  I've found that I can do a `pcs resource cleanup vmware_fence` to cause it to start back up again in a few seconds, but why is this happening and how can I prevent it?

 vmware_fence	(stonith:fence_vmware_rest):	Stopped
