[Mailman-Users] "could not acquire qrunner lock", etc

[Bill Bradford]

I've got some fairly high-traffic mailing lists (sunmanagers, with ~3K 
members, sunhelp with ~1K, and 3 or 4 others with ~500 members).

Upgraded to Python 2.0 this morning, and recompiled/reinstalled 
mailman 2.0.3 along with it (had already been running this version,
but I figure recompiling/installing it along with the new python
wouldnt hurt).  I started getting a lot *more* of these in 
/usr/local/mailman/logs/qrunner than normal:

Mar 23 10:47:06 2001 (29208) Could not acquire qrunner lock
Mar 23 10:48:03 2001 (29234) Could not acquire qrunner lock
Mar 23 10:49:01 2001 (29246) Could not acquire qrunner lock
Mar 23 10:50:04 2001 (29272) Could not acquire qrunner lock
Mar 23 10:51:02 2001 (29300) Could not acquire qrunner lock
Mar 23 10:52:02 2001 (29313) Could not acquire qrunner lock
Mar 23 10:53:03 2001 (29325) Could not acquire qrunner lock
Mar 23 10:54:02 2001 (29336) Could not acquire qrunner lock
Mar 23 10:55:03 2001 (29381) Could not acquire qrunner lock
Mar 23 11:01:03 2001 (29527) Could not acquire qrunner lock

At this point, I looked at the crontab, and changed the qrunner
line to this (I figured it was trying too often):

# Retry failed deliveries once per minute.
1,15,30,45 * * * * /usr/local/bin/python -S /usr/local/mailman/cron/qrunner

Now, I'm seeing this in qrunner:

Mar 23 11:15:03 2001 (29811) Exception reading qfile: /usr/local/mailman/qfiles/

Mail is getting through, although sometimes mail I sent to a small list
(< 100 members) might take 5-6 hours to arrive - and this is to my account
on the *local machine*.  Any suggestions?  Seems I've been seeing these
delays since upgrading > 2.0.1.  

MTA is Sendmail 8.11.x, local delivery agent for local mail is procmail.
OS is Solaris 8, on a 300Mhz SPARC AXe-based machine with 128MB of RAM,
and plenty of drive space.

Thanks.

Bill
