Hi all,

Those are instances. Depending on how the application is built more than one instance can be initiated (like with Nautilus and Mozilla). The amount of memory displayed is the total shared memory used by the instance. So if there are five Nautilus instances each displaying 20MB used, the total used is 20MB, not 20x5=100MB.

Type this to see a tree of processes:
Code:
ps auxf
the KDE also has a nice system guard tool, including task manager that could display the same information.
