Люди, сталкиваюсь с такой проблемой - freebsd начинает сбоить на боевом сервере, иногда считалка трафика которая по ipfw show показывает статистику правила ipfw count дает сбой вида:

sockstat: sysctl(): No such process
sockstat: sysctl(): No such process
sockstat: sysctl(): No such process

чего делать? я так понимаю надо увеличивать надежность! вот мой конфиг ядра:
