[Mailman-Users] Mailman Using 70- 90% of CPU

It looks like someone else is having the same problem:

Also when I stop mailman with mailmanctl stop, I get the following in the 
qrunner log, with only Outgoing having a different message (about the 
SIGTERM -- have no idea if this means anything):
May 02 13:43:32 2003 (22561) Master qrunner detected subprocess exit
(pid: 22566, sig: None, sts: 15, class: NewsRunner, slice: 1/1)
May 02 13:43:32 2003 (22561) Master qrunner detected subprocess exit
(pid: 22564, sig: None, sts: 15, class: CommandRunner, slice: 1/1)
May 02 13:43:32 2003 (22561) Master qrunner detected subprocess exit
(pid: 22568, sig: None, sts: 15, class: VirginRunner, slice: 1/1)
May 02 13:43:32 2003 (22567) OutgoingRunner qrunner caught SIGTERM.  Stopping.
May 02 13:43:32 2003 (22567) OutgoingRunner qrunner exiting.
May 02 13:43:32 2003 (22561) Master qrunner detected subprocess exit

In answer to Will Yardley's question to my previous message:
>What happens if you kill those processes? What about if you stop, and
>restart mailman (via mailmanctl)?

As soon as I restart Mailman, it uses up around 70-90% of my CPU with the 
outgoing Runner job.  It's not one run away job, I can recreate it in less 
than a minute.  And we haven't sent out any messages today, mailman has 
just sent some sub/unsub notices out.

I had this problem as I said on our old machine, I just figured it was 
underpowered.  But the problem hasn't gone away with a much faster machine, 
different OS, different web server.
