> What appears to happen is that I kill nsclient so nagios_cron starts reporting "stale" at 3000 seconds,  and the same for base_log_checks shortly after.  Then about every hour I get more "stale" soft alerts, and then after the third try it goes to a HARD alert and I still get a ticket, though I'm not sure why it's even checking if execution should be disable when nagios_cron is in a warning state.  But not only does the active checks (service_is_stale) get executed but I'm also still getting notifications sent after 3 attempts, so it doesn't really appear to be doing anything.  Unfortunately right now these servers are so busy it's hard to put them in debug mode.  Have I missed something obvious with these?

I must say though, with the size of your environment, it's quite possible that
just looking up the dependency takes longer than it does to just execute the
extra check. If you're looking to save time, that might well bite you in the
ass. It's something that will probably be improved til Nagios 4, but it will
require a change in Nagios' object structure, so we can't really do it without
upping the major version number :-/

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
