Ah, I recognize this now. This is a minor bug that I believe has been fixed for 1.5.0. It only affects packing; it has zero impact on your application. The bug occurs when filling the object_ref table for packing. If you interrupt the pack operation while the object_ref table is being filled, the corresponding entry in object_refs_added will not be created and the next attempt to pack will try again and stumble in exactly this way. The bug has been solved by replacing entries in object_ref rather than just inserting them. The object_ref and object_refs_added tables are only used during packing. Perhaps the quickest thing to do is remove only the offending entries: delete from object_refs_added where tid = 255911127406517196; delete from object_ref where tid = 255911127406517196; A bit of trivia: that error message says that object 2714 in transaction 255911127406517196 has at least one direct reference to object 893440.
