I think i have run into https://bugzilla.redhat.com/show_bug.cgi?id=1435207.

However last comment is from 2017-05-17.

Since all vm:s on the host is getting unresponsive the only thing i can do to fix it is to restart vdsmd.

That works for an hour or so but then all vm:s getting unresponsive again.

Does anybody know if there is a workaround for this bug?
