Public bug reported: During testing we found that if 220,000 instances match the updated_at criteria in _heal_instances they are all pulled from the db which can lead to huge memory usage and the oom killer stepping in. The large number of updated_at instances could happen organically, but in our case was triggered by the _run_pending_deletes compute periodic task updating a large number of instances.
