Eventually it will reach a point where every list object is cached and a maximum sized message has been handled, and it will stop growing. Eventually, all 4 OutgoingRunners will reach this size (unless this size is due to processing an anomalously large message, but that doesn't appear to be the case here as large messages also affect IncomingRunner). There are threads on this in the archives. Some relevant ones are at <http://mail.python.org/pipermail/mailman-users/2007-December/059332.html>, <http://mail.python.org/pipermail/mailman-users/2008-July/062359.html> and <http://mail.python.org/pipermail/mailman-users/2010-March/069075.html>. In particular, see the post at <http://mail.python.org/pipermail/mailman-users/2010-March/069078.html> which includes a patch to disable list caching in the qrunners if you want to try that, but I suggest you first just wait, and I predict the memory growth will slow and eventually stop and it won't impact performance because at any given time most of the memory is inactive and will be swapped out if needed for other processes. Also, you can add up all the sizes of the lists/*/config.pck files to get a very rough idea of how much things may grow. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
