1000+ processes then Nagios fails

[Shane_Seidel at gwf.com.au]

Hi All,

We have a dual P3-1200mhz 512M RAM server running Nagios 1.0 monitoring 180
devices and 800 services.

I have noticed that the number of nagios processes increase until they reach a
count of approx 1000 at which time the server complains it is "out of memory"
and starts shutting down services.

I found that executing '/etc/rc.d/init.d/nagios reload' from cron would "solve"
the problem. The number of processes would return to approx 60 and then start to
climb again. I have the cron job execute every 30 mins.

I took the config and put all the hosts, services, etc into Netsaint 0.7 on a
P2-350Mhz 128 mb RAM and processes rarely rise to over 100 and then return to
40-60.

Note that I use the "default" option while compiling to maintain backward
compatibility for Netsaint.

Has anyone else experienced this? Is there any way to restrict the number of
processes used by nagios. Note also that the big server also runs MRTG/RRD on
approx 20 devices, although mrtg process complete

Any help appreciated
Thanks
Shane
