Hi Nicholas,
Thanks for this. Indeed, that was the problem. I opened the vdsm log and
saw a lot of exceptions like this:
2019-01-28 10:56:54,792+0000 INFO (jsonrpc/2) [vdsm.api] FINISH

TaskStateError: Operation is not allowed in this task state: ("can't

I migrated all VMs to a different host, forcibly rebooted the SPM host
and now the event stopped showing.
Thanks.
Regards.

Hi Nicolas,
We had a similar issue and it was caused by a stuck task in VDSM on
the host that was the SPM.
We found that VDSM tasks don't always show up in the oVirt GUI. You
can check using 'vdsm-client Host getAllTasksStatuses' on the SPM
host.
We could not manually cancel any of the stuck VDSM tasks or move the
SPM to another host. The only solution we found was to migrate all
the VM's off that host and restart it. Once the remaining hosts had
contended to be the new SPM, we gave the engine a restart too.
Hope that helps,
Nick

Hi,
We're running oVirt 4.1.9 (I know there's a new version, we can't
upgrade until [1] is implemented). The thing is that since some
days
we're having an event that floods our event list:
Clearing asynchronous task Unknown that started at Tue Jan 22
14:33:17
WET 2019
The event shows up every minute. We tried restarting the
ovirt-engine,
but after some time it starts flooding again. No pending tasks in
the
task list.
How can I check what is happening and how to solve it?
Thanks.
