[ovirt-users] Hosts flapping between non-responive and active

Hi guys, I have a problem with hosts tha are flapping between NON-responsive and Active. The network is performing well, the VM's are running fine when it happens all the time. I also move a host to a Local Storage DC only without any NFS share attached and even there it happens. In the logs, vdsm.log on the hosts and the engine.log on the engine does not show anything wrong what refers to this behaviour. Where can I look for more information ? My hosts are on the latest 4.1 VDSM versions: Engine: oVirt Engine Version: 4.1.7.6-1.el7.centos Cheers, Matt
