Что если включить debug, в логах что-то меняется?
включение дебага указывает на вот такой симптом:
readv() not ready (11: Resource temporarily unavailable)
Как это можно лечить?
Это нормально.
Возможно, однако после большого количества сообщений о недоступности
ресурса я вижу вот такие сроки:
Если бы "readv() not ready (11: Resource temporarily unavailable)"
имел хоть какое-то отношение к ошибке, то он бы логировался хотя бы на
уровне info. Но никакого отношения к ошибам данная ситуация не имеет -
просто вот так вот устроен epoll в Линуксе, что приходиться читать
до ошибки EAGAIN, иначе можно пропустить конец файла.

но при этом файл не продолжает отдаваться и через некоторое время
соединение обрывается.
Подскажите, пожалуйста, куда копать.
Я правильно понимаю, что /linux-source-2.6.20.tar.bz2 проксируется
с бэкенда ?
