Also some strange: after resart I see 100% busy on CPU#1 (other CPU as before -- from 0.05 to 0.4). This is busy loop over kevent: kqfd 11 cl 0 nc 0 eventlist 813400000 nevent 200 timeout 0.2000000 ret 11 errno 0 ev_kqueue.c:128 Like some events not removed from eventlist and permanently re-activated.
