Hi,

It seems that there is a fix for that bug, merged to 4.4 only (not
backported): https://gerrit.ovirt.org/105325
It fixed bug BZ 1663615
<https://bugzilla.redhat.com/show_bug.cgi?id=1663615> which seems to deal
with that issue.

Can you please consider upgrading to the latest 4.4 version for solving it?

Regards,
Sharon
