I had install ubuntu 64 bit on my system (ubuntu 12.04 lts).

When I do free -m 

             total       used       free     shared    buffers     cached
Mem:          5859       5284        574          0        251       4012
-/+ buffers/cache:       1021       4838
Swap:         6032          0       6032

I have total 6GB of RAM, now even I had just one application in used it show me 5284 are totally used, only 574 MB of memory is free.

What to do to resolved it or to debug it ?

Also when I fire TOP command, it show only few application running as in my system, but occupied memory are very much?

Use system monitor to see which process is devouring all your memory to get a possible idea of what you should do next.

You can do the same with top; use Shift + < / > key combos to select the memory usage column, and Shift + R to toggle the reverse-state of column sort.

You can then kill the process that's causing the problem.
