Re: [monit] Problem with monit's "not monitoring" status

[Alex Soto]

I've seen problems where long running monit procesess(months) stop  
being able to start things while running the start command works fine  
manually.

Interestingly, I've only experienced it with a single ruby daemon  
(ar_mailer) so maybe it's related since you're using backgroundrb.

A simple restart of the monit daemon fixed my problem.
