Всем привет!
Столкнулся с проблемой спам/флуд/DoS атаки приводящей к отказу сервера без автоматической возможности восстановления его работы (ручной килл процесса и ручной запуск).

Но как только я отключаю RevEmu, то проблема сразу исчезает. Это не пустые слова. Я столкнулся с данной проблемой более полугода назад - выключил RevEmu проблема не возникала полгода, а вчера включил снова и сервер снова уводят в отказ без авто-рестарта. То есть когда он ложится, то последнее что есть в логе сервера это спам-флуд выше.
