I'm running mailman 2.1.13 on Ubuntu 9.10 out of the Ubuntu repositories. Mail server is postfix and I also have Apache and spamassassin on the same box, again all from the ubuntu repositories.
Over the last couple of weeks I've noticed that a number of legitimate e-mails have failed to be delivered. All of these have been shunted and an error like the one repeated below is written to the error log.
I've been through the mailman FAQ, the launchpad documentation and bugs for the ubuntu maintained package and googled a bit. I'm none the wiser about how to fix this problem.
2558 is the pid of the incoming runner,
