Maybe: Without the "fsync" (as Tim pointed out, even with "fsync", but maybe more rarely), the order in which blocks are written to persistent storage is not deterministic. If you are unlucky, the last transaction may have been written correctly but earlier blocks are not written when a crash happens. When the application starts again, it may not recognize that part of its storage is corrupt. On the other hand, as the index file is probably not written, the restart should try to rebuild the index file and then detect the corruption. Thus, maybe not an issue... -- Dieter _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
