memory usage

[Jeremy Hanmer]

I'm having  an incredibly hard time tuning nagios to monitor all our our
services without using up all of it's 2 gigs of RAM within a couple of
hours.

There are approximately 4000 services being watched with a check
interval of between 5 and 15 minutes.  Out of these, about 1200 are
being passively submitted.  nagios -s tells me I should be running
approximately 86 max concurrent processes.  While the other machine
cruises along with 200, this machine ends up running out of memory
within 2-3 hours regardless of whether I set the max procs to 100 or 400
(anything less, and the latency is horrible).

I currently have a dual PIII 800 with 1 gig running netsaint 0.0.6
monitoring the exact number of services, but this dual 1ghz machine with
twice the RAM can't keep up.  It's using mysql for all of the data.

Does anybody have any idea?
