Re: Restarting Resin freezes monit

[Martin Pala]

Hi

i have tried to replicate your problem but it works for me without 
problems. My configuration:

--8<--
check apache with pidfile /var/run/apache.pid
   start program = "/bin/su - apache -c '/etc/init.d/apache start'"
   stop program = "/bin/su - apache -c '/etc/init.d/apache stop'"
   if failed host localhost
      port 80 protocol http
      and request "/test"
      with checksum ad38ebf120253979403a4d2dcbc0105b
      with timeout 30 seconds
      then restart
--8<--

If i changed file 'test' by appending some string to it, monit detected 
the checksum failure and tried to restart apache. I'm running monit 
4.4-beta5. Can you try it? You can find it at: 
http://www.tildeslash.com/monit/beta/

Btw. you can use native monit setuid like this (example from documentation):

  exec "/usr/local/tomcat/bin/startup.sh" as uid nobody and gid nobody


Thanks :)

Cheers,
Martin
