As always, it would be *really* interesting to know just what those
processes are doing; apparently the FreeBSD command is 'ktrace'.
Is sendmail refusing to read more data, or is mailman refusing to
send it, or what?
> My (brand new) Mailman installation locks up when posting messages about

> mailman 39004 /bin/sh -c /usr/local/bin/python -S /usr/local/mailman/cron/...
> mailman 39005 /usr/local/bin/python -S /usr/local/mailman/cron/qrunner
> root 39007 sendmail: server localhost [127.0.0.1] child wait (sendmail)
> root 39008 sendmail: TAA39008 localhost [127.0.0.1]: data (sendmail)
> Is there a timeout setting that should be increased?
