Не работает Keep-Alive

Description (last modified by san)

У пользователя два блока:

3U с платой VE-02 и модулем r422
Vip с модулем r422

Между блоками организовано соединение через Ethernet(спутниковый канал) и передаются/принимаются данные r422 через это соединение. На этих блоках с этими же настройками пользователь уже достаточно долго проводит тесты, 4 апреля было зафиксировано странное происшествие:

Пользователь не передавал данные
В какой-то момент клиент отобразил состояние подключение Error. затем начал делать циклические попытки соединиться с сервером.
При этом со стороны сервера подключение продолжило отображаться в состоянии "Connected", хотя ожидалось, что подключение будет разорвано по истечению таймаута Keep-Alive+некоторое время. (пользователь ожидал время значительно большее чем значение таймаута)

Настройки устройств:

В логе сервера(детализация INFO) за это время не появилось ни одной надписи.
Лог клиента(к сожалению сам момент разрыва отсутствует во фрагменте лога)

Пользователь вышел из этой ситуации перезапустив VE-02, воспроизводимость проблемы не известна.

з.ы. В нашей сети есть VIP(192.168.0.1) и 3U с платой VE-02(192.168.1.52) доступные для экспериментов. Могу отметить что в моих экспериментах разрыв по Keep-Alive срабатывал всегда.

Проблема воспроизвелась снова, в этот раз пользователь запустил tcpdump:

Время на блоках одинаковое.
tcpdump запущен так: tcpdump -v -s1514 host 198.18.1.34

Проблема воспроизвелась снова,

Логи VIP:
Apr  7 10:00:38 comcerto daemon.err sip_ua[437]: r232.cpp:250: module 1: cannot connect: Connection refused

А почему опять лог приведен не полностью? Фрагмен начинается с попытки установки нового соединения. А где начало события, то есть потеря имевшегося соединения?

follow-up: 6 comment:4 by san, 6 years ago

Видимо сколько было, окно терминала возможно не большое. Спрошу у пользователя есть ли начало.

Не стоит, это же не имеет отношения к проблеме. Просто меня удивило приведение фрагмента лога, который начинается заведомо позже произошедшего события... :)
