See: CPU states: 17.8% user, 0.0% nice, 81.7% system, 0.5% interrupt, 0.0% idle on any (tested on P2-45) machine. CPU is used by SYSTEM, not by USER. So I can't restrict it with login.conf And load average can be up to 20-40 :( Please don't redirect me to -questions, it's a kernel problem, not just config. Dmitry.
