Hi

I'm trying to remote debug Sun IDM which is running on Sun AppServer 8. I've installed the remote pack, and edited domain.xml as per the instructions.

Then, I shut down my domain (asadmin stop-domain), went to Netbeans, and attached my profiler. All working fine, I can see the memory usage starting to go up as the server starts, but then it hovers around the 50Mb mark, but I can see that in reality (from prstat) that my appserver is actually using something like 2.5Gb.

So, I'm wondering if I am profiling the wrong thing. Can anyone shed some light on this for me please?

Thanks!

Profiler displays the size of the Java heap, while (AFAICT) prstat
displays the size of entire process.
