Hi Seagal,

to investigate issues/problems people will often ask you to run a command over the command line ( shell ) and in response, you should copy&paste the output of such a command in your next post for further investigations. ( use the "insert ... Code" - feature of the forum for such a copy&paste, so that it's easier for people, to read the answer. )

Are you sure that you're not confusing ram with disk space? Unless you have runaway memory-consuming applications running on your server, it doesn't look like your memory usage has deviated much from your first report.
