Множественные запросы Flask, Gunicorn, ведение журнала Nginx не работают

Я провожу тестирование производительности в своем приложении Flask.

  ngnix -> gunicorn -> flask

Лог-файлы:

• access.log ОК
• gunicorn.log ОК
• api.log Только показан 1 запрос

Я использую инструмент для тестирования пресса. Мои запросы обрабатываются правильно и правильно регистрируются в файле журнала Flask в моей среде разработки (MacOS 10.10.5).

ab -c 10 -n 10 -A username:password https://1.1.1.1:8443/api/1.0/echo/

Когда я перехожу к производству (Ubuntu), я не вижу, чтобы все 10 запросов регистрировались в файле журнала Flask. Я вижу только 1 в файле журнала API. Инструмент ab сообщает, что все запросы обрабатываются правильно.

Я вижу 10 запросов в Ngnix, Gunicorn, но не во Flask.
