Also, is WAS 6.02.17 a network deployment configuration? If so, consider that
ALL of the WebSphere components, Deployment Manager, Node Agent, and
EACH server region have their OWN JVM. This can quickly add up to more
resources than you ever encountered previously.
Compared to WAS 4, WAS 6 will look exceptionally pig-like. We're running a
multiple application workload with WebSphere 6.01.xx and we don't have a
768Mb JVM. I don't know how many concurrent users this application has, or what
your Java methods are doing, etc.
We have multiple servers with different apps in them, and on average our JVM
sizes are 128MB min and either 256 or 325 MB max. We let WebSphere grow
the JVM if it needs to. We also cluster the WebSphere to another set of app
servers on another Linux guest. This spreads the workload to multiple JVM
instances, which improves the overall performance of the individual JVM. That
said, my development WebSphere cluster machines are 1.4 gigs (Primary
node) and 1.0 gigs (secondary node) and my production nodes are 2.1 GB and 1.8
GB respectively.

Hank, what's the complete java command look like? "ps axwwww" should show you.
We're looking to see what all the flags/switches on it. Also, what
kernel version?
