Description Gordon Watson 2016-10-12 19:16:38 UTC 
Description of problem:

The customer has three hosts in the only cluster in this RHEV 4.0 environment. From time to time, all encounter "Heartbeat exeeded" timeouts and, within that time-frame, sometimes go non-responsive.

They have 'vdsHeartbeatInSeconds' currently set to 20.

The customer has disabled Power Management to prevent hosts from getting fenced.

RHEV-M runs inside a VM within a VMWare environment.
