<DIV><FONT face=Arial size=2>I have had a problem for the past 4 months on my
RHEL 3 AS server on<BR>which I installed Postfix and Mailman. After I
migrated from Red Hat<BR>7.3, I've not had peace with this server (the RH 7.3
host was running<BR>Postfix and Mailman as well). I have the server
updated with all errata<BR>and I compiled the Fedora SRPM for mailman
1.2.4-4. I have roughly<BR>1,300 users.<BR><BR>The problem is that the
server hangs. The daemons start to die and the<BR>server only functions at
the kernel level. You can remove the network<BR>cable and it notifies you
on the console. You insert the network cable<BR>and it also notifies
you. If you browse to Webmin, it responds with the<BR>authorization page,
but authentication fails because the daemon died. <BR>You can telnet to the
server on different ports and it connects, but it<BR>waits for the login banner,
etc.<BR><BR>I made a script which logs the load on the server each minute and
when I<BR>look at this I realize mailman is the problem. The load average
goes up<BR>to 60% (?) when normally it's only 4%. I browsed the mailman
logs and<BR>for the last few hangs, log entries coincide with mail sent to
lists,<BR>but it happens with small or large lists.<BR><BR><skip explanation
of mailing lists><BR><BR>The hanging of the server is happening whether mail
is sent to the small<BR>or large lists. I've tried troubleshooting the
hardware and through<BR>testing I'm able to send mail to the lists and the
server hangs, but not<BR>every time. This makes me thinkg it's not postfix
or mailman, but<BR>possibly some other daemon.<BR><BR>I also installed another
server for testing with 1,900 users. Using the<BR>same configuration it
does not hang and all email is sent in a timely<BR>fashion.<BR><BR></FONT></DIV>
