Very strange, I've never seen Linux cache 100% of the memory used. For example, out of 1024MB total RAM I have 295MB of RAM used, out of that RAM being used 295MB is cached. So in theory, my OS is not using any memory nor are any of my applications right? Why does my cached RAM in "free" always show the used RAM?
Code:
# free -m total used free shared buffers cached
Mem: 1024 295 728 0 0 295
-/+ buffers/cache: 0 1024
Swap: 0 0 0
