Ребята как можно это трактовать?

Вот собственно прихожу на работу с утра и как гром среди ясного неба - сервер который полтора года работал бес сбоев упал! Причем упал странно - пингуется, но ни один порт недоступен (превышен интервал ожидания), после ребута в ДЦ просмотрел логи и увидел вот такие вещи:
