У меня небольшой роутер на openwrt.
Примерно через день работы падает ppp сессия и подняться заново не может. Пробовал --nobuffer, --loglevel 0 - безтолку.

Где то встретил что проблемы с объемом трафика. Но рядом машина на Debian-е у которой сессия висит пока не отключишь. Может есть какой то счетчик трафика который необходимо обнулить? Ведь на устройстве всего 16 Мб ОЗУ.

Вот такой лог:
