I have noticed that in both Conky and Top that my memory usage is reported as really high - at the moment, Top reports that 13.1GiB of 16 are in use; only 4.6GiB are available (roughly, that's sort of a moving target.) Conky reports roughly the same. When the computer first boots it uses only around 500 megs. It doesn't appear to be a memory leak as it isn't climbing any higher. The system monitor is showing roughly the same thing. In neither Top nor the system monitor can I find a particular process that is responsible. It not causing stability problems. It's just sort of odd. 17.3 rarely went over 1GiB.
Any help or insight is appreciated.
