Yes. This is because Nagios remembers that it has sent an alert for
the problem state, and therefore it sends the recovery alert as well.
IIRC, this was a feature requested on the list quite some time ago.

Same thing here, I'm afraid.

Unfortunately I'm on my home windows box right now, so I can't check the
sources properly, but it goes something like this:

if (have_sent_problem_notification(host, contact))
	send_recovery_notification(host, contact);

I'd be willing to take a patch to make this configurable, but you'd have
to come up with a neat name for the config option and some documentation
for it, cause I can't for the life of me think what to name or how to
explain something like that.
