Re: Monit can't restart Courier IMAP?

[Martin Pala]

Monit sets minimalistic environment for security reasons, the PATH for 
example is set to:

 PATH="/bin:/usr/bin:/sbin:/usr/sbin"

In the case that your courier-imap rc script referred to some object 
which is not in this path (for example under /usr/local/...), or other 
environment variable, then it can fail (when you run command from shell, 
you could have customized environment).

Solution could be to set the environment in monit's method definition or 
fix the rc script.

  stop program = '/usr/local/bin/bash -c "PATH=$PATH:/usr/local/bin 
/usr/local/etc/rc.d/courier.sh stop"'

You can also add something like: 'env >> /tmp/courier_env.$$' to the rc 
script to see what environment you have when started from monit and what 
when started from shell.
