Ops....
The linux box halted again, after 12 hours operating normaly.

The more strange is that there isn't any message in the /var/log/message,
the system simples stop to respond, and some strange behavior is that the
TOP comand gaves me :

... others...

Meanning that the Load Average is incompatible with the use of the CPUs.

I really have no idea where to find some clue about what is going on.
