[Mailman-Users] Mailman locking up, seems to be Spamassassin related

[Chris Croome]

Hi

One a CentOS 4 box, running Mailman that comes with the distro, I'm
seeing locks up every now and then -- all the lists on the machine stop
processing mail.

When this happens a restart gets things moving again.

This is the error that is written to /var/log/mailman/error:

 Jun 26 12:04:58 2006 (28052) Uncaught runner exception: (4, 'Interrupted system call')
 Jun 26 12:04:58 2006 (28052) Traceback (most recent call last):

Mailman has been set up to work with Spamassassin using the instructions
here:

  http://www.jamesh.id.au/articles/mailman-spamassassin/

As far as I can tell the only thing that this involves is this line
being added to /etc/mailman/mm_cfg.py:

  GLOBAL_PIPELINE.insert(1, 'SpamAssassin')

(I didn't set this machine up however...).

Does anyone have any ideas what could be going wrong here and what might
be don't to fix it...?

Thanks

Chris
