Hi Andreas, Thanks for answering .
I have more or less followed the documentation on how to tune nagios. service_reaper_frequency=2 max_concurrent_checks=0 service_interleave_factor=s host_inter_check_delay_method=s The host check command is check_icmp We use nagios 2.7.1 The nagios server is not overloaded 4Go RAM and dual core 3GHz. But still the nagios latency is increasing for no particular reason ... see the graph attached. Cheers Ben Andreas Ericsson wrote:

After a couple of days, without any change, and even though the execution time and the Nagios server load remain the same the latency slowly increase. It seems that it is an exponential growth.All the checks kicks in later and later, no exception.Usually after a week the latency is up to 60seconds and after 2 week up to 5 minutes.I have currently set up a Nagios restart every monday, but I would like to find a better solution and understand why does the latency keeps increasing.We monitor over 50 hosts and have over 1400 checks every 5 minutes. The nagios server is quite big and is not really loaded. Any Idea would be appreciatedThree things to check: service_reaper_frequency check_interleave_factor max_parallell_something_something I haven't done my morning routine yet, so you'll have to figure out thereal variable names in case my memory is a bit off (which it no doubt is).Other than that.. What nagios version are you running, and how is your host check command defined?
