Hello,
We run a VPS running Debian with Mailman 2.1.11 and Postfix. Python is
2.5.2.
Up until a couple of weeks ago, we were running a number of quite small
mailing lists (max 200 members) with no problems. But then we imported
the subscriber list of a list that we'd moved from Yahoogroups that
contained 800+ members, and that's when the trouble started.
This list not only has 800 or so members, but it's a fairly active list.
We also have quite a number of deferred messages from Yahoo in the queue,
but that's a different story. We've just implemented DKIM, hopefully that
will help sort that one out.
The problem we're seeing is that if the list gets any way busy, the memory
usage of the python process that runs Mailman skyrockets, dragging the
system to a crawl.
We're a little clueless as to how to debug this further, so any help would
be appreciated.
Geoff.
