About [5] https://bugzilla.redhat.com/show_bug.cgi?id=1917707, I have found
that when executing the http request of the playbook, sometimes in the
response there are some events that are missing. The way we handle the
events is via while loop, where in each loop we continue from the
lastEventId. Since not all events were listed, the lastEventId (which is
returned as total number of events) is smaller than the actual eventId that
was handled. Thus, in the next iteration the last events are handled again.
It seems that this comes from Ansible Runner, and I'm investigating that
area now
I'm not sure if it's the same issue as you get with the logs, though, as
I'm not familiar with this area in the OSTs. Is the creation of the 2 logs
done by different threads?
Regarding the initial error (' directory is not empty.non-zero return
code') I'm not sure, will have to loop more into it. Martin, do you have
any idea?
