@feld @mint I think that this theory is the very likely cause. I've updated FluffyTail to the same Oban version bump commit (dbf29cbae4) on Sunday and it finally broke under it's own weight. I've seen an increase in CPU iowait and disk backlog alerts that must be associated with the Oban v12 jobs migration, because nothing else has changed. I've also noticed a big increase in DB timeouts in the logs. Granted it's running on a garbage tier Frantech VPS with the DB being hosted on a slab with dmcache on the OS drive.

I'll leave the instance in its current failed state if you want more information.

My test instance (@phnt@oban.borked.technology) running on the cheapest OVH Cloud VPS is still working perfectly fine after a week and a half of 4x the traffic FluffyTail receives.
