High cache usage
Although my site currently doesn't have any visitors memory is 100% used with cache taking a big part…
Before my site was active, in random occasion cache would jump from 10% to 50% when I had no visitors at all.
EDIT:
Sovled ->
I guess I need to find another way is my sever OOMING.

Look at "vmstat" output at the "si" and "so" values (NOT the first line; you need to do something like "vmstat 5 2" and look at the last line) to see if actual swapping is occuring.
On your graph, look to see if the "buffers" gets small or if the "swap" line grows.
