to disable metalayer-crawler0: add "exit 0" after the first command line of /etc/init.d/metalayer-crawler0 file, or replace command line for start and restart command with command line for stop ( dsmtool -k ...... ).

switch off and reboot, it works now.

media player can also work after this change.

(except one time, i have not encount high load display again. it seems that it is of use.)

wish this helps.
