Seems there's a misunderstanding of how linux is using memory. Refer to
the documentation about buffers and chached values reported by vmstat,
top, free, etc!

Check the used memory with the command free! It may look like this:

$ free
             total       used       free     shared    buffers     cached
Mem:        515620     457116      58504          0     180712     137532
-/+ buffers/cache:     138872     376748
Swap:       995984        212     995772


Free memory is 376748 KB referring the line starting with +/-, where the
use of memory for buffers and cache already is recalculated.
