Hey everybody,
I've hit a snag when configuring parents for hosts. First a
little bit about our setup.
Most of our hosts have only one connected ethernet interface (if
you don't count the management cards). Still, we have quite a
handful of hosts (over 100) that have two interfaces.
Up until now

Hi!
Actually, this was both my and Nagios' fault. You see, faced with
a config block like this:

foo=baz
Nagios will see... nothing. The trailing \ in the first line

Nagios 2.6 and 2.5 have memory leaks. They are not that big that
within hours your machine will be swapping, but they degrade

The other day, we got our beefier machine. I had hoped my latency
problems (ever increasing check latencies) would go away or at
least turn irrelevant with that. They didn't.
More precisely: we have migrated to a four-core Opteron 2.2GHz
with 2GBs of RAM and a quite fast I/O Subsystem.
