Monit fails to stop apache processes

We have setup monit to restart apache when logging is over 60%. It tries to restart but fails.

[MST Apr 14 10:51:33] info     : 'apache' trying to restart
[MST Apr 14 10:51:33] info     : 'apache' stop: /etc/init.d/httpd
[MST Apr 14 10:52:33] debug    : M/Monit: status message sent to http://[10x.xx.xx.x94]:8080/collector
[MST Apr 14 10:54:33] error    : 'apache' failed to stop (exit status -1) -- no output

We thought it was probably because it takes more time to stop the process and we increased the timeout to 180 seconds like this:

   check process apache with pidfile /usr/local/apache/logs/httpd.pid
     start program = "/etc/init.d/httpd start" with timeout 60 seconds
     stop program = "/etc/init.d/httpd stop" with timeout 180 seconds
     if failed
     host phoenix.example.com
     port 80
     protocol apache-status loglimit > 60%
     then restart

Now looks like it waits for that amount of time and still fails. The main purpose to use Monit is to restart when logging is heavy and it is never able to restart.

The apache process is at /etc/init.d/httpd. Any help greatly appreciated.
