Plugins » Katello

Nondeterministc reproducer (not real user story, but worth for developers/testers):

1) stop foreman-tasks service (to populate katello_event_queue a bit)
2) generate several hundreds candlepin events (i.e. (un)register a Content Host with an activation key, or remove all and attach back a subscription pool to another Host) - do that in a loop until katello_event_queue has few hundreds of messages
3) start foreman-tasks service - leave step 2) running (at least I did so, it might but not need to be important)
4) Once ListenOnCandlepinEvents task consumes the backlog, check if katello_event_queue has zero queue depth (see #c7)
5) if there some messages constantly acquired but not acknowledged, you got it. Otherwise, goto step 1).
