I'm starting to understand what's wrong with my hub. I had the queueworker plugin activated and after one of the upgrades it started to fail because of a missing table (but I didn't have any failed db migrations). Sadly I lost the log by now, it got rotated away.
However, I deactivated the queueworker plugin but still have a huge amount of entries stuck in my queue. Is there a way to fix this without dropping the entries from the queue? Some way to force re-delivery.
Thank you
