Thanks for pointing out the difference. However, in this case I'm trying
to find out what consumes RAM specifically, not virtual memory in
general. Besides, from all I can see, the high memory usage is NOT
caused user space processes. So the output from ps was just to show that
even though some hundred MB of RAM (!) are used, just some few MB are
consumed by processes.

Kind regards
Martin
