Всем привет !

Столкнулся с проблемой, никак не могу понять в чем причина.
Суть проблемы - nginx не хочет отдавать через mod_zip по https-у то, что я хочу забрать =)
По http отдает.

Схема стандартная - запрос к бэкенду, который возвращает нам

Content-Type: application/zip
Content-Length: 126488906
Connection: keep-alive
Accept-Ranges: bytes
Content-Disposition: attachment; filename="Arch.zip";
X-Archive-Files: zip
Cache-Control: max-age=0

После чего конкретно на этом архиве я качаю до 46,9-47,1 МБ. после чего у меня все отваливается с такими вот записями в логе

Дальше чистится память

Очевидно где-то какой-то таймаут. Вопрос где ? И почему по http такого не наблюдается ?
Заранее благодарен.
