наше программное обеспечение, содержащее:
centos, nginx, http-сервер kestrel, приложение dotnet core (v2.0.8) работают с mongodb (v3.6.7)
http сервер kestrel иногда перестает отвечать, похоже, что ошибка при подключении драйвера mongodb, как показано ниже, регистрирует в 3-й строке
что вызывает эту проблему?
Я настроил параметр макс. Открытых файлов на 640000 с этой темой

но ничего не исправлено, пожалуйста, вы можете помочь решить эту проблему, спасибо всем.
