[Mailman-Users] mailman processing queued messages - not working

[NetC Network Support]

Hi,

Our mailman installation is not processing queued mail. Postifx 
delivers it (relay=mailman) and it ends up in the qfiles directory. 
After that, nothing happens to it.

System info:
- mailman 2.0.3
(ports i think)
- FreeBSD 4.8
- Postfix

Processes:
mailman 20016  0.0  0.0   628  244  ??  Is   11:50AM   0:00.00 /bin/sh 
-c /usr/local/bin/python -S /usr/local/Mailman/cron/qrunner
mailman 20018  0.0  1.1  7308 5832  ??  S    11:50AM   0:00.24 
/usr/local/bin/python -S /usr/local/Mailman/cron/qrunner

Active mailman cron entries:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/local/bin/python -S 
/usr/local/Mailman/cron/qrunner
27 3 * * * /usr/local/bin/python -S /usr/local/Mailman/cron/nightly_gzip
0 5 1 * * /usr/local/bin/python -S /usr/local/Mailman/cron/mailpasswds
0 12 * * * /usr/local/bin/python -S /usr/local/Mailman/cron/senddigests
0 17 * * * /usr/local/bin/python -S /usr/local/Mailman/cron/checkdbs

N.B. Lock files get created (qrunner.lock) with a timestamp of 21st 
December at 21:50, even though the system time is:
Tue Dec 21 12:06:36 EST 2004

-rw-rw-r--  2 mailman  mailman    63 Dec 21 21:50 
qrunner.lock.<hostobscured>.20018
-rw-rw-r--  2 mailman  mailman    63 Dec 21 21:50 qrunner.lock

Only logfile being updated recently is qrunner:
(taken at 12:05)
-rw-rw-r--  1 mailman  mailman   1685161 Dec 21 12:05 qrunner
-rw-rw-r--  1 mailman  mailman   3893027 Dec 21 11:02 smtp

Containing nothing but:
(etc.)
Dec 21 11:45:01 2004 (19962) Could not acquire qrunner lock
Dec 21 11:55:01 2004 (20070) Could not acquire qrunner lock
Dec 21 12:00:01 2004 (20152) Could not acquire qrunner lock
Dec 21 12:05:02 2004 (20191) Could not acquire qrunner lock

Steps I have tried: (all unsuccessful)
- sending test messages
	these hit postfix which delivers them to the mailman q
	the web interface does not show any pending administrator requests
	these lists all require approval
- restarting the qrunner process
- running qrunner by hand - no error output
- removing the lock files
- restarting cron
- removing all qfile directory contents and sending test messages

I must be doing something wrong. Everything was working until 5:05pm 
Friday (now 12:15pm Tuesday AEST). Nobody changed anything that I know 
of.

Any pointers would be appreciated.

Thanks,
