[ovirt-users] oVirt Engine 4.0.5 and CentOS 7.3 Instability

Hi oVirt Gurus, Happy new year to everyone !!! 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. Anyone with this kind of problem ??? [image: pasted1] After reboot : [image: pasted2]
