A few of my ISPConfig/CentOS 5 boxes have a Postfix hiccup every Sunday night for the past month. I have this in my maillogs - Oct 1 00:00:45 server postfix/postfix-script: stopping the Postfix mail system Oct 1 00:00:53 server postfix/smtpd[19053]: warning: database /etc/postfix/virtusertable.db is older than source file etc/postfix/virtusertable Oct 1 00:14:09 server postfix/smtpd[13746]: table hash:/etc/aliases(0,lock|fold_fix) has changed -- restarting Oct 1 00:15:59 server postfix/smtpd[19053]: table hash:/etc/aliases(0,lock|fold_fix) has changed -- restarting Oct 1 00:13:21 server postfix/master[28578]: terminating on signal 15 Oct 1 00:17:09 server postfix/postfix-script: fatal: the Postfix mail system is already running Following this, Postfix is down until I start it.
Does this really only happen on every sunday? Then you should have a look at your weekly cronjobs if one of them affects postfix. ISPConfig has no cronjob that is run weekly, all cronjobs are at least run once a day.
No, not every Sunday. It's happened 2 weeks in a row on a Sunday for one server, and just happened on another server on a Sunday.
Maybe it's a good idea to install monit on your servers. It can restart Postfix if it finds it isn't running: http://www.howtoforge.com/server_monitoring_with_munin_monit_debian_etch http://www.tildeslash.com/monit/index.php
To solve the error: Code: Oct 1 00:00:53 server postfix/smtpd[19053]: warning: database /etc/postfix/virtusertable.db is older than source file etc/postfix/virtusertable It is my understanding to run the command: Code: postmap /etc/postfix/virtusertable -- For the error: Code: Oct 1 00:14:09 server postfix/smtpd[13746]: table hash:/etc/aliases(0,lock|fold_fix) has changed -- restarting Try running: Code: newaliases The only time I've seen a similar error was went both the alias_maps and alias_database where not correct. What is your output of: Code: postconf alias_maps alias_database I have no idea about the Sunday issue. Cheers
alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases This issue happened again on Sunday. I have tons of these errors in my maillog: postfix/smtpd[11070]: warning: problem talking to server private/anvil: Connection timed out postfix/smtpd[10060]: table hash:/etc/aliases(0,lock|fold_fix) has changed -- restarting
This is occurring a few times a week now. It happened last night. Wierd thing is that my maillog.2 ends at Oct 28, maillog.1 has nov 4 from midnight to 4:30am, and then maillog starts at 4:30 am . When postfix looks dead - If I try to run /etc/init.d/postfix stop it fails and I see postfix is still running. I have to kill this process before I can start postfix again. I see a lot of this in my maillog, postfix/postfix-script: fatal: the Postfix mail system is already running
It looks like syslog AND ISPConfig are rotating a maillog. Could this be causing a conflict? I see maillog, maillog.1, maillog.2, etc and maillog.31-10-07_23-59-01, etc etc
ISPConfig is just making a copy of the mail logfile to analyze it, it is not rotating the main logfile. But to be sure you can try to change the time of the ISPConfig mail log cronjob (in the root crontab) to run a few minues earlier or later.
You can try to comment out the mal log script from ISPConfig in the root crontab file for one night and see if potfix does not crash then.
