[Supervisor-users] controlling postfix status

[Pablo Moreno]

Hi,

I'm configuring supervisord to check postfix status and restart it if
needed.

Here is the supervisor daemon config file:

[program:qa-postfix81-241]
command=/usr/libexec/postfix/master -w -c /etc/postfix/81-241
autostart=true
autorestart=true
startretries=3
stderr_logfile=/var/log/supervisor/qa-postfix81-241.err.log
stdout_logfile=/var/log/supervisor/qa-postfix81-241.out.log
loglevel=info
user=root

After starting supervisord, postfix service is started, but its master
process (dummy foreground) is restarted every second.

But, meanwhile, postfix background process is not restarted. And If I stop
postfix background process, supervisor restarts it.

[***@server log]# /usr/sbin/postfix -c /etc/postfix/81-241 status
smtpd81-241/postfix-script: the Postfix mail system is running: PID: 29377

So, why in the supervisor log file the master process is being restarted
every second?

thanks in advance,
pablo.
