I have VMWare install CentOS 5.5 and deploy some java application. I want to know how much memory remain, As I use command below, All memory is use. But when I check with top command, all process use “0.0%” of memory. So I want to know what happen? What really memory usage on this VM?

Answer
i think your system is problem. Can you reboot system and check again.
For my system:
