Performance issues, too

[Daniel Meyer]

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 instantly after a restart
   of nagios

- the latency skyrockets after "some time", its not like "six hours
   after the restart" or something like that

- service check execution time does NOT change at all, it stays on
   the same level all the time

- changing from a dummy host check to "adaptive" host checks back and
   forth doesn't make a difference

- i see memory usage rise proportional to the latency, but there is
   way enough free memory left (this morning it was 150 seconds latency
   but still 790 Megs free ram, plus one gig cached)

- load on the system rises a little but not much

- network usage goes down (well there are less checks done due to the
   latency, so no surprise here)


Details of my setup can be found in the "big performance issue..."-thread, 
if needed i can repost them here...
