- on database update, execute garbage_collection(). This ensures a proper closed db and written cache

- on sql errors returning (and not triggering an error) execute the rollback too

both "bugs" resulted in transactions left open if a query returned an error on database update preventing a clean update. Symptoms being for example oracle users not having all database info updated, the version number not changing or config variables not written.
