Тайм-аут при получении сообщения с пулом Mongo Connection с использованием java

В производстве мы подключаемся к MongoDB с помощью Java (пул соединений). Каждый день мы получаем почти 500 запросов с приведенной ниже ошибкой (MongoSocketReadTimeoutException), и мы не используем никаких сложных запросов. Может быть, это устаревшие соединения Mongo?

Я не видел проблем с нашим кодом или медлительностью MongoDB. Пожалуйста, просмотрите мой код ниже и предложите, нужно ли добавить какие-либо параметры или что-то изменить.
