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.=20 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. ************************************************* "Para ser exitoso no tienes que hacer=20 cosas extraordinarias.
