It appears that the file /usr/local/cpanel/3rdparty/mailman/lists/<listname_you_elided>/requests.pck is corrupt. You can see what's in it with /usr/local/cpanel/3rdparty/mailman/bin/dumpdb. If you just remove the requests.pck file, I think that will solve the problem, but first use dumpdb to see if there are any real requests. ** Changed in: mailman Status: New => Incomplete ** Changed in: mailman Assignee: (unassigned) => Mark Sapiro (msapiro) -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1350280 Title: Bug in Mailman version 2.1.18-1 To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1350280/+subscriptions
