I am running my ubuntu desktop 12.04 to host 1 site on it. The machine is good, but i have a little problem.
CPU: MD FX-6200 /3.8G/X6/BOX AM3+
RAM: 8GB DDR III 1333Mhz
When i check my ram usage i got this:
and something the server use all 8 GB ram and the site stop work. Any ideas from where come the problem and i can't understand what is really memory usage Mem or +/-buffers/cache, because the difference is big.
total used free shared buffers cached
Mem: 7970 6907 1062 0 38 6039
-/+ buffers/cache: 830 7139
Swap: 8173 0 8173
