Benjamin, just out of curiosity : do you use ndomod ? I experience similar problems; I had a healthy Nagios install (1200 host, 7000 services, active+passive) with nagios 2.3 After upgrading to Nagios 2.9 with ndo-utils, I have 'latency-peaks' every day/few days. I'm in the middle of testing if it's related to the new Nagios version or the extra system load from ndo-utils, or a bug in ndo-utils.
I'll keep the list informed.
