     &amp;gt; If you can help us with your wisdom to our discussion at following link we would really appreciate it. (You can reply from/to this maillist entry, i will add/attach them to the forum)

     First thing you need is to show output of &quot;top&quot; command. 
    

    

    

    

     Second, output of: 
    

    

     fgrep memory /var/run/dmesg.boot
