I suspect you has no memory leak at all. It's very typical for Unix systems
to keep free memory as small as possible (here is 11M only from 2G) :

last pid: 79350;  load averages:  0.39,  0.46,  0.41   up 33+17:16:00  09:43:53
21 processes:  1 running, 20 sleeping
CPU states: 25.8% user,  0.0% nice, 11.4% system,  9.8% interrupt, 53.0% idle
Mem: 103M Active, 1430M Inact, 378M Wired, 83M Cache, 63M Buf, 11M Free
Swap: 2096M Total, 4872K Used, 2091M Free

  PID USERNAME   THR PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND

      location ~ \.(html|css|js)$ {
          expires ...
      }

      location ~ \.(jpg|jpeg|gif)$ {
          expires ...
      }
