...etc...
that use much much RAM!

Also,
/usr/sbin/mysqld --basedir/ --datadir/var/lib/mysql --usermysql --pid-file/var/lib/mysql/plain.mr-hosting.net.pid --skip-locking
/usr/sbin/mysqld --basedir/ --datadir/var/lib/mysql --usermysql --pid-file/var/lib/mysql/plain.mr-hosting.net.pid --skip-locking
/usr/sbin/mysqld --basedir/ --datadir/var/lib/mysql --usermysql --pid-file/var/lib/mysql/plain.mr-hosting.net.pid --skip-locking

use much CPU...

What I can do now?

Thanks...
