I stop the service and the problems seems it disappeared. My question is why 
this work before with the service up and why is not working?

Subject: Re: CPU problem

Do you have the cpu hotplug daemon running?  Run "/etc/init.d/cpuplugd
status" to check.  It will vary on and off cpus automatically.  You
can turn it off with "/etc/init.d/cpuplugd stop" and "chkconfig
cpuplugd off" to not start it at boot time.
