Greetings. This may be 'working as designed' but I'm not sure....

If anyone has seen this please feel free to enlighten.

We have a WebSphere cluster, with WebSphere in Network Deployment 
configuration. This means that the primary node has a configuration slightly
different than the secondary node in that the primary has a deployment manager 
task. That in and of itself causes a nearly 600 meg difference in
memory footprint.

WebSphere on Linux for z/Series is a 31 bit task, running in a 64 bit operating 
system. I've verified that both machines are at the same maintenance
level, and both are indeed 64 bit SLES.  So the conundrum here is why would the 
node with the deployment manager consistently have almost twice as
many resident pages above the bar as the node without the Deployment manager? 
Is there some function of the Deployment manager that would request
memory above the bar to a much greater extent than the node agent or the app 
server tasks?

Just curious as we'd like to explain the behavior difference.
