Проблема с сетью в Hetzner

Здравствуйте, уважаемые.

Приобрел сервер в Hetzner (XS 13). Стоит Debian 6, RAID 6 на семи 3ТБ дисках. Имею очень странную проблему с сетью (или она меня имеет :(). При закачке любого большого файла сеть полностью падает (http/ftp/torrent). Сервак не пингуется, помогает только ребут.

При этом при работе под их rescue-system все работает как часы. И скорость закачки, кстати, существенно выше (для тестов качаю файл ~70Gb с их же бекап-сервера). Система стоит чистая. Качаю wget'ом. Время падения - 1-30 минут, рандомом. В логах - девственная чистота.

В дц божатся, что никаких ограничений с их стороны нет, параметры роутера для сервака под rescue не меняются.

Пробовал ставить убунту - ровно та же картина.

Может, кто-то сталкивался с подобной штукой?

Заранее спасибо всем откликнувшимся.

Покажите выдачу вот этих команд:

cat /var/log/messages
dmesg

И сразу все станет ясно.

P.S. торрент в Hetzner запрещен

На счет торрентов - Вы уверены? Не видел такого. Собственно, мне надо, чтобы они неделю нормально проработали. Потом можно вырубить будет :).

Дорого покупаю настоящие сайты. Не инвестирую деньги и не беру кредиты.
