[Mailman-Users] mailman is very slow...

[Troy Campbell]

For some reason our Mailman installation has gotten very slow.  One
email distro took about 17 hours according to the user.   There is data
flow as I can see by running the "mmdsr" stat script.  I googled and
found something about qfiles can grow too large  but don't have any in
my /var/lib/mailman directory.  I also went through a checklist I found
online to tell if Mailman was hung and didn't see anything that this
matched.

The version of Mailman we are running is:

mailman-2.1.9-4.el5  on Red Hat Enterprise Linux Server release 5.2
(Tikanga).  

 

Also bouncing mailman "appears" to make it run faster for a short while
when looking at the maillog but I could be imaging things.

 

I saw some of these errors from the mmdsr script:

It appears those files do not exist now.  The Hourly summary of Posts,
Post count by List,  and Post Count by Sender is in the low thousands or
hundreds.  I bounced Mailman multiple times as well as bouncing postfix
thinking the system was hung before investigating the stats.  I'm going
to go home now as I've been fighting this all day but will check back
later.

 

Any help is truly appreciated,

Troy
