97% Memory, Static Server w/ Nginx


I have a server serving static content running only Samba and Nginx. the memory is at 97%, command "top" confirms 97% full, but non of the proceses taking that much as "top shows"

What might be the reason.

Code:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                 
11476 nobody    20   0 19808 3992 1428 S  1.7  0.1   3:04.38 nginx

explains alot. thanks.
only weird thing is it doesnt do it on other servers that i have such as dev environment.

I will have to look into how centos decides to reserve that space.

Thank you for your reply.
