RE: [monit] monit not monitoring

[Gilad Benjamini]

Thanks for your answer.
If that's the case, then the FAQ entry in
http://mmonit.com/wiki/Monit/FAQ#init is misleading; it recommends to add
"stop all" to the script, possibly causing this problem. I think the FAQ
entry should also include a recommendation to "start all" in that case.

How does 5.0 change the behavior in the general case ? How does it change it
in the unclean poweroff case ?
