I have seen such a behaviour when a colleague moved the storage file without stopping the ZEO server and then copied a new storage file at the old place. Under *nix, moving/deleting a file does not affect processes which have this file opened. Such processes continue to work with the open file. In the case described above, the ZEO server continued to use the old storage file and ignored the copy. Of course, as soon as the ZEO server was restarted, the new ZEO server used the copy -- and did not see anything that went into the moved away storage file. In our case, the moved file was still present and we could recover all modifications. If we had removed the file instead of moving it, then only experts able to restore deleted files would have been able to get our modifications back. -- 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
