Как повторить:

cat packet.dump | nc 1.1.1.1 4701

1.1.1.1 - адрес сервера версии 2.0.5
4701 - порт

packet.dump - приложен.

Alex Kirhenshtein

Спасибо, будем смотреть.
Я удалил пока дамп из сообщения.

2c2i

Если слать на порт 4747 - проблема тоже повторяется

Victor Kirhenshtein

Исправили. Исправление войдет в 2.1-М1 и в 2.0.6. В аттаче патч для 2.0.5 на случай если собираете из исходников.
