Jesse,
Top says Mem: 513276K av, 361416K used, 151856K free, 38080K buff,
183584K cached. So it looks as if the used and free memory adds up to
the total memory. However, if I check this in KDE system guard and break
it down some more, it turns out the application memory is only 142544 +
buffered memory 38080 + cached memory 183616 = 364240Mb.
So from this it appears that something is cashing RAM, or to put that
another way, some process has acquired 183616Mb of RAM and is holding on
to it. The reason I think this is in RAM not swap space on the
harddrive, is that a reboot gets rid of the cached figure, wherever it is.
Or am I just reading this wrongly?
