Здравствуйте.

FreeBSD 7.0-RELEASE FreeBSD 7.0-RELEASE #6: Sun Nov 23 14:32:31 EET 2008     root@ddd:/usr/src/sys/i386/compile/blabla70  i386
В качестве ВПН-сервера для предоставления услуги доступа в Интернет используется mpd4.

Всё работает нормально, но раз в неделю возникает ситуация:
У абонентов рвётся впн-соединение (причём не у всех сразу, а рандомно). При попытке подключиться пишет "Ошибка 742 при попытке установки соединения", с пятой-десятой попытки проходит.

Со стороны сервера в логах следующее:

После /usr/local/etc/rc.d/mpd4 restart всё нормализуется.

У кого-нибудь есть предположения, как исправить ситуацию? :(
Может ещё какую-нибудь информацию предоставить?

Можете более точно натолкнуть на опции, на которые следует обратить внимание?

Для начала необходимо попробовать обновиться до 7.1 STABLE.
Для чего включен MPPE? Попробуй отключить MPPE тоже.
На счет тюнинга - вопрос спорный. mpd может спокойно терминировать и более 1к одновременных коннектов без особых плясок с бубном.
Когда у меня возникли подобные проблемы с mpd я отключил всякие шифрования, сжатия и т.п. Это лишняя дополнительная нагрузка.
В твоем случае мне кажется поможет обновление системы, с выхода 7.0 очень много поменялось. И если клиентов много и это тривиальная раздача интернета - то сразу отключи лишние фичи в mpd.

нехватка системных ресурсов
может конечно и пофиксили в какойто версии mpd незнаю
но лучше поискать в гугле

Эммм... В текущих 6 и 7й ветках, например net.graph.maxalloc = 4096. Подняли его еще полгода назад.
