    I have had a problem for the past 4 months on my RHEL 3 AS server on
    which I installed Postfix and Mailman. After I migrated from Red Hat
    7.3, I've not had peace with this server (the RH 7.3 host was running
    Postfix and Mailman as well). I have the server updated with all errata
    and I compiled the Fedora SRPM for mailman 1.2.4-4. I have roughly
    1,300 users.

    The problem is that the server hangs. The daemons start to die and the
    server only functions at the kernel level. You can remove the network
    cable and it notifies you on the console. You insert the network cable
    and it also notifies you. If you browse to Webmin, it responds with the
    authorization page, but authentication fails because the daemon died.
    You can telnet to the server on different ports and it connects, but it
    waits for the login banner, etc.

    I made a script which logs the load on the server each minute and when I
    look at this I realize mailman is the problem. The load average goes up
    to 60% (?) when normally it's only 4%. I browsed the mailman logs and
    for the last few hangs, log entries coincide with mail sent to lists,
    but it happens with small or large lists.

    <skip explanation of mailing lists>

    The hanging of the server is happening whether mail is sent to the small
    or large lists. I've tried troubleshooting the hardware and through
    testing I'm able to send mail to the lists and the server hangs, but not
    every time. This makes me thinkg it's not postfix or mailman, but
    possibly some other daemon.

    I also installed another server for testing with 1,900 users. Using the
    same configuration it does not hang and all email is sent in a timely
    fashion.
