как я могу освободить соединения mongodb?
У меня есть сервер mongo с высокой скоростью чтения / записи за короткое время. Я использовал python и pymongo, проснувшись сегодня утром, я обнаружил, что никакое соединение не может быть установлено с мастером mongod, потому что оно достигло 19992, это довольно пугающее число
, даже если я остановил всю программу, номер соединения не изменился
