See http://thread.gmane.org/gmane.science.linguistics.wikipedia.technical/49500 When the servers were switched, the second half transaction for those files would have failed and half-rollbacked. We already suffered this kind of failures in the past, see bug 15430, bug 20744, bug 24978. Seems that each ~12 months we suffer one of those. It should finally be fixed. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
