</span>Can you describe how you've performed the upgrade? Did you upgrade<br>
Engine first and then all the hosts (it is highly recommended to upgrade<br>
host one at a time, and move each to maintenance mode before doing so)?<br>
When did the troubling log appeared?<br>

</span>Can you share your vdsm.log of that time? I wish to understand what<br>
