I'm planning a test environment with WAS-ND version 7.latest 32bit on Solaris 10 running in a virtualized environment. In order to maximize the number of nodes that I can run, I want to try and minimize the memory footprint for each node. By default, it appears as though the heap size is roughly 250MB on a node agent that I just started up. If I set -Xmx back to something like 128m for the node agent, what kind of risk would I be running?

Are there any node agent tuning guidelines?
