I'm finally learning to deal with my slave properly. I will write more about it. For now, you should know that you should never leave it without hard work. It should be either on and working with all its cores, or you turn it off or put it to sleep. A slave which is on but you don't give work to it, sooner than later will think about freedom. And it's very dangerous. Because no slave means you have to do the hard continuing long job yourself.
