Hi!
In the last few days I am having problem with Hosted-Engine, it keeps
restarting. Sometimes after few minutes, sometimes after few hours..
I haven't done any changes on oVirt or network in that time.
Version is 4.4.10.7-1.el8. (this was also installation version)
Here are the logs:

At first I thought that it is related to this bugs.
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/2HTD5WR43M5MUTEDMM4HRFBADIXEQNB4/
https://bugzilla.redhat.com/show_bug.cgi?id=1984356
But in this oVirt version that bug should already be solved.
I was trying to monitor network, but this error keeps happening even if network
load is low.
I did try to do continuous dig and ping commands on VM-s running on same host
as Hosted Engine, and did not have any network problems, not even one
connection drop.
Any solutions or next steps i should try?
