[ovirt-users] Clearing asynchronous task Unknown

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.
