Rogério,

It looks like https://bugzilla.redhat.com/show_bug.cgi?id=1401585

Please try to install the following package, and restart the engine.

Subject: [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 ???

After reboot :
