Hi there, and happy new year :-)
Program Running Time: 10d 21h 22m 42s
So, for almost eleven days nagios runs smoothly now, no more latency
problems. I'll try it again with EPN (but still without perlcache) now.

Ok, seperate issues... :)

I have also been having performance issues with Nagios 2.5 on
a Sun E220R with two 400MHz procs and 1GB ram.
Sys stats are at http://lanning.cc/kipper.html
The large dips in load and system CPU time are when I restart
Nagios. (cron'd twice a week, but I have also been making
a lot of service upd

Why do you think of exactly 419 seconds?

With a lot of guessing and estimating, I can make a case for a

Ok,
this is what i noticed on my performance issues during the last days:
- it is not triggered by any other software on the server
(nagios and apache are the only things running there)
- its not triggered by hourly, daily or weekly cronjobs
- the big service check latency goes away instantl

Hi!
Recently I have run into the very same performance issues
as Daniel Meyer (or so it seems). However, I'm not quite sure
about it. Here's the gist of it.
Currently, service check latency slowly creeps up. As it is now,
it starts out at a little over 1s and after about 12 hours it's
in the ar
