There is nothing to solve here. If you're machine has free memory processes like apache and other services are going to reserve it so your server can handle more requests. What use is free unused memory to a computer?

It's time to add memory if your server starts to use swap actively. Until that time there is nothing to worry about.

Yeah linux doesnt track free memory like it would on windows. Youve got "free" memory which isnt doing anything, and cached memory, which is effectively the same thing as free memory, except its cached whatever it was you were doing before.
