for some reason I'm using up all my ram on linux and its pretty much a clean install of FC7 running 3 servers... on 4g ram heres screeny

anybody know why this could be?

you are using a good amount, try sorting by memory usage. hit h while in top for help and setting info

I figured it out it was the linux filesystem cache using everything up I found a usefull command went from using almost all of my memory to only 600megs heres the command if anyone is running into way too much mem usage

Code:

echo 1 > /proc/sys/vm/drop_caches

Yes, you can clear caches if you want. However there is no benefit for that as Linux kernel uses free memory to speedup disk i/o when there is memory available. High cache amount pretty much just tells you you have a lot of memory to spend.
