Do you know there is a huge volume of mail waiting moderation for this
list? If there is, it seems a possible cause.

You could look at the data/heldmsg-listname-nnnn.pck files 

========

No such files under /var/mailman/data/ Doing a find under /var/mailman/
reveals none....

========

with
bin/dumpdb and delete what you don't want with bin/discard (the clean
way to do it) or you could just make a list of all the
data/heldmsg-listname-nnnn.pck files older than a couple of days and
feed that to bin/discard.

Another thing you could try is just bin/dumpdb on the
lists/listname/request.pck file to be sure it can be read.

========
Looks like it can be read.

[root at vuwunicosmtp004 bin]# ls -l ../lists/mailerdaemon/request.pck
-rw-rw-r--    1 mailman  mailman        20 Feb  2 08:15
../lists/mailerdaemon/request.pck
[root at vuwunicosmtp004 bin]# ./dumpdb -n
../lists/mailerdaemon/request.pck
[----- start pickle file -----]
<----- start object 1 ----->
{'version': (0, 1)}
[----- end pickle file -----]

========

So your web server isn't choking waiting for this one Cgi to respond.

========

Doesn't look like it, one CPU (of four) seems totally utilised...but
that leaves me 3.

>Where to start looking for why this particular list is faulting please?

In addition to the above, there may be clues in Mailman's error log or
the web server logs.

=========

I get this from the mailman error log,

[root at vuwunicosmtp004 bin]# more /var/log/mailman/error

And I get this from the httpd log,

==========

Is this a bug or a config error on my part?

Steven
