[Mailman-Users] Slow Outgoing Queue

Hello,

I am having trouble with a slow outgoing queue.  I am running Mailman 
2.1.6 on FreeBSD 4.11.

Here is an example of a slow email traced through Mailman's logs:

At 10:18, a message is sent to the moderated "students" list I host, 
and held:
logs/vette:Nov 08 10:18:28 2005 (3640) Students post from 
[email at address.hidden] held, 
message-id=<43707B8E.17015.163FEC at localhost>: Post to moderated list

At 10:24 the moderator approved the message for posting:
logs/vette:Nov 08 10:24:25 2005 (91201) held message approved, 
message-id: <43707B8E.17015.163FEC at localhost>

At this point, if I understand correctly, the message should be sitting 
in queue/out, waiting for a queue-runner process to send it out.  There 
were between 80 and 100 .pck files in queue/out at this time.  What is 
the outgoing qrunner doing?  Eating RAM, mainly:

# ps auxwww | grep OutgoingRunner
mailman   3641  1.2  9.5 107680 99240  ??  S    13Oct05 288:04.50 
/usr/local/bin/python /usr/local/mailman/bin/qrunner - 
--runner=OutgoingRunner:0:1 -s

That process appeared to remain fairly idle, using over 100M of RAM for 
almost an hour:

logs/post:Nov 08 11:18:45 2005 (3641) post to students from 
[email at address.hidden], size=5383, 
message-id=<43707B8E.17015.163FEC at localhost>, success

And finally, actual delivery went out at a modest but acceptable 
6msg/sec
logs/smtp:Nov 08 11:18:45 2005 (3641) <43707B8E.17015.163FEC at localhost> 
smtp to students for 1642 recips, completed in 252.164 seconds

Any idea what is causing the holdup for outgoing messages?  Any tips 
that will help me trace this down?  Thanks in advance.

	- H
