Cougaar Mac OS X

Hi all,

I am quite new to Cougaar and initially trying to identify how powerful and
reliable the platform can be. I am currently running a very simple
experiment, trying to see how many agents I can support in one node. The
experiment is very simple, I have a HelloWorld Plugin which just uses the
log shout to print a Hello World and I also get the address of the current
Agent to make sure I print messages from each one of my Agents. I then
create with a script 100, 500 and 1000 Agents respectively. The experiment
runs for 100 and 500 Agents but not 1000. I am using a Mac OS X Leopard as
the development platform at the moment with JSDK 1.5 and NetBeans 5.5.1. I
would appreciate any help.

The message I get can be seen below with the 1000 Agents experiment:
