I have gone mad in the past trying to make individual mem segments
equal total memory. Evidently different diagnostics compute on a
different basis. For one thing kernel mem seems to be reserved off the
top, and for another, there are certain memory blocks 'reserved' on
boot - I don't know why or whether they are released later. Unless you
want to spend some time getting to the bottom of this - in which case
I would be eager to hear what you discover - I would recommend you
drop that question and concentrate on your original question: which
program is using the memory?

What results have you had from top?

I do not see what use ps is to discover the leak...
