Hello, I'm a bit confused because all memory is being used by some process but I don't know which one.

Hi, Have you tried checking under top? You can install "htop" and run that. With htop you can sort by cpu usage and mem usage etc. See what results you get from there. Cheers, K
Well, htop shows 2006/7976MB memory usage and about the same MEM% as ps but how come /proc/meminfo shows a full memory and htop only 2GB/8GB?
It seems that /proc/meminfo is giving the incorrect info as I've just checked mine, and it also shows that I only have +-126mb free of 2048mb., but according to top/htop, I have 50% free.
