I packed our zope-database (zope 2.6.2), but after a while this error appears: Site Error An error was encountered while publishing this resource. exceptions.ValueError Sorry, a site error occurred. Traceback (innermost last): * Module ZPublisher.Publish, line 150, in publish_module * Module Products.PlacelessTranslationService.PatchStringIO, line 44, in new_publish * Module ZPublisher.Publish, line 114, in publish * Module Zope.App.startup, line 166, in zpublisher_exception_hook * Module ZODB.Connection, line 551, in setstate * Module ZODB.FileStorage, line 645, in load * Module ZODB.FileStorage, line 620, in _load ValueError: I/O operation on closed file What caused this error? In the var-dir there are (among others) following files: 780M Mar 19 01:35 Data.fs 162M Mar 19 02:25 Data.fs.pack Can I assume that Data.fs.pack is the newly packed database and is not corrupted or incomplete? Or do I need to replace it with a backup? Thanks, wouter www.vrijschrift.org www.opencursus.org
