These are kernel threads. 5.x is more modular than 4.x and a lot of functionality has been moved to internal threads (for the sake of SMP). There's really nothing wrong with this; esp. since the number of threads is still pretty small :) The kernel may create more such threads if it needs them; like e.g. when using GBDE or so. > The machine in question is a > very simple fetching mail server running on a 500mhz Via Eden Mini-ITX > board. I'm using the same hardware here. It is more than fast enough for this. Don't worry about those kernel threads, which are idle most of the time. The CPU time they consume would have been used up in 4.x too (as system time), you would just not see it with ps there as you can see it here. > Steven Lake > -Owner/Webmaster > Raiden's Realm > www.raiden.net Cheers, -cpghost. -- Cordula's Web. http://www.cordula.ws/
