okay, my original impression wasn't valid in the longer term.
In fact, with as fast as the two servers break each other now, I don't
know how it was working when I wrote my original email below.
The problem basically is the two nagios servers fight like mad over
things like passive/active checking, etc. Splitting the xrddb_database
settings doesn't help, and splitting the xsddb_database kinda defeats
the whole idea. That the xsddb_database stores things like
notifications_enabled and checks_enabled are the issue. I wish that it
didn't keep that kind of stuff in a "status" table, but, oh well.
Looks like sending over nsca checks from an active checker to a passive
central server is the way to go.
Bleh. This is going to be a mess.
