Solaris 10 - memory management confusion

Hello

i have a Problem - my Server is running with following MEM Information (from TOP):

Code:

Memory: 32G phys mem, 4195M free mem, 10G total swap, 9788M free swap

So i think - no problem, 4GB Free, not swapin.

So - our programmer wants to know what process taking how much memory - i searched...
prstat shows me:

Code:
