This is a common misunderstanding of the output of free. The memory statistics you showed do not indicate excessive memory use. On the contrary, they show only about 2.3% of system memory in active use by programs.

If you look more closely at the first line of numbers, you will see that 7928420 of the 8124068 memory pages in use are being used to cache data. This memory is, for all intents and purposes, free. Your operating system it using it to improve system performance, but can throw the cached data out and reallocate the memory for other uses more-or-less instantly if the memory is needed elsewhere.

To see whether you actually have a memory shortage, you need to look at the second line of numbers, which adjusts the totals by treating buffers and cache as free memory rather than used (because, again, if needed, that memory can be reassigned instantly). Looking at that line, you will see that only 182400 pages are in use for "real" data, leaving 7975776 available.
