Hi, My Zope instance (2.6.2) doesn't alert or log anything about ZODB corruption at startup or when browsing, but when I try to compact it, I got this error: Error Type: CorruptedError Error Value: C:\Program Files\Zopista_2_6_1\var\Data.fs:9676045:time-stamp reduction: 0342993b626b50b3 <= 034abe992d2f1aa2 The full traceback is...

Is there another solution than exporting root folderishes and importing them in a clean new instance ? Many thanks in advance for your hints. -- Gilles Lenfant Pilot Systems - 66, rue de Provence - 75009 Paris Tel : +33 1 44 53 05 55 - www.pilotsystems.net Hébergement Zope et Plone gratuit - http://www.objectis.org
