Default Nexus 4, KitKat 4.4.2: 100% CPU

Hi!

Sometimes, out of nothing, my Nexus 4 heats and the 2nd core locks down at 100%. The temperatures raises to more than 34 (battery) and 48 (cpu) Celusius.

I tried to kill every application and service, one by one, but none of them changed anything. The only solution is reboot.

Anyone knows what's happening?

Thanks.
Regards.
