recently upgraded to 4.2 and had some problems with engine vm running, got that cleared up now my only remaining issue is that now it seems ovirt-ha-broker and ovirt-ha-agent are continually crashing on all three of my hosts.  Everything is up and working fine otherwise, all VMs running and hosted engine VM is running along with interface etc.
