I found that altq is the problem. When i turn on pf only with rules my box behaves normally. When i turned on altq rules in one second my whole cpu was used. what was strange that i didn't change rules in some significant way. I checked them and i found that i left one rule like this pass all on pfsync0 i have added this rule when i was messing with pfsync iface. I forgot to remove it. When i removed this rule everything come back to normal state. This quite strange that this rule can cause such big mess on system. Is it some kind of bug ?? -- Best Regards: GiZmen UNIX is user-friendly; it's just picky about its friends UNIX is simple; it just takes a genius to understand its simplicity
