Иногда nginx не отправляет данные обратно в браузер (ERR_EMPTY_RESPONSE в Chrome).
После проверки журнала ошибок сервера я обнаружил эти странные сообщения:

Кто-нибудь знает, почему это происходит? Через некоторое время все снова будет подано правильно.
я нашел эта ветка русского форума это говорит, что это связано с open_file_cache директивы.
Имеет смысл, поскольку я использую Sublime Text и он не сохраняет атомарные файлы.
У меня была такая же проблема, после многих поисков, ее разрешил open_log_file_cache
open_log_file_cache max=20000 inactive=30s min_uses=2;
Это не связано с вашим вопросом, но для других посетителей, которые ищут лучшие практики кеширования файлов nginx, это моя полная конфигурация кеширования файлов после многих поисков и выполнения многих тестов.
# cache information about FDs, frequently accessed files

open_file_cache_valid 120s; # Sets a time after which open_file_cache elements should be validated.
open_file_cache_min_uses 2; # Sets the minimum number of file accesses during the period configured by the inactive parameter
