I update oVirt Engine to 4.0.5 from 4.0.4 and Centos to 7.3 from 7.2 last week and after that I have instability four times. Every time ovirt engine seems to loose communication with one or more node servers like this image below. Every time I rebooted oVirt engine server and everything came back to normal. It'd be great if you could share logs - engine.log from the Engine and vdsm.log from the host(s). Y. Anyone with this kind of problem ???
