Ian,
I appreciate the info. This is what I did and this is what I got.
I edited the following files:
capsd-configuration - max-suspect-thread-pool-size & max-rescan-thread-po=
ol-size both are set to 1
collected-configuration - collectd-configuration threads =3D 1
poller-configuration - poller-configuration threads=3D"1"
I rebooted the host ( 1 Ghz, 256 RAM, REdhat v7.2 )
Go get coffee...

I've reloaded the box twice and the same thing happens. I'm overrun with j=
ava processes and it brings the machine to its knees. Not sure what I did =
wrong.
Any thoughts appreciated.

Greg - I just tuned my OpenNMS setup down to use one thread for
discovery, and one for polling (one for the actual polling and one for
rescans ...)
With this tuned down I get approximately 48 procs in the filesystem ...
and lots of free memory on a machine with 256MB (I'm using ps -ef | grep
java | wc -l to find out ... I have Tomcat turned off at the moment and
nothing else running other then postgresql).
Is this what you see?
cheers
