Hi, I sometimes got this in random (?) places in a Zope 2.6.1 box Error Type: VersionLockError Error Value: ("'\\x00\\x00\\x00\\x00\\x00\\x00\\x04\\xfe'", '/stuff/versionMenus') The traceback... Traceback (innermost last): Module ZPublisher.Publish, line 102, in publish Module Zope.App.startup, line 200, in commit Module ZODB.Transaction, line 235, in commit Module ZODB.Transaction, line 349, in _commit_objects Module ZODB.Connection, line 391, in commit - __traceback_info__: (('BTrees._IOBTree', 'IOBucket'), '\x00\x00\x00\x00\x00\x00\x04\xfe', '') Module ZODB.FileStorage, line 726, in store VersionLockError: ("'\\x00\\x00\\x00\\x00\\x00\\x00\\x04\\xfe'", '/stuff/versionMenus') Tere's something I can't understand : * The "/stuff" folder has been removed for a long time * This error raises on objects with no connection with that "/stuff", even when browsing ZPT in the Zope help... Is my ZODB corrupted ? How to get rid of this ? Many thanks in advance. --Gilles
