Nothing wrong. Its basically the way top works. When a process
terminates, the memory is not reported as freed until a new
process needs it. In other words, the memory used as reported
by top is a "high water mark" in the memory, with some exceptions.
What you need to do is to monitor the use of the swap. If you
*ever* see it seriously used, then you have indeed used all your
memory. Your computer looks to me like its running just fine &
hummin' along. :-)
