non-blocking test scheduler (faulty service slows down monit)

[ethaniel 1]

I have a service (sphinx) which on start immediately gives a "permission denied error". For some reason it's blocking monit for 30 seconds every time it is started, even though when I start it by hand it returns the error instantly.

I am using monit 5.20.0

What I don't understand is why doesn't monit check other processes in those 30 seconds? The error is returned instantly, I would assume that a faulty program should not halt monit for 30 seconds.

Monit currently performs the checks serially and waits for up to timeout seconds for the process to start.

We will implement new test scheduler in Monit, which will provide non-blocking tests and will allow to run tests in parallel.
