Я использую Mule Mongo Connector для выполнения некоторых операций в Mongo DB. Я использую его на некоторое время, не имея этот вопрос, но теперь у меня есть это исключение после запуска на некоторое время мой поток в Mule:Исключение, определяющее maxBSONObjectSize/connection, было отказано, поскольку слишком много открытых соединений с использованием Mule Mongo Connector

Я имел взглянуть на оболочку ./mongod и I ВСЕГДА есть эта ошибка, когда у меня открыто более 200 подключений:
Sat Aug 31 23:33:13.417 [initandlisten] connection refused because too many open connections: 204
Sat Aug 31 23:33:13.420 [initandlisten] connection accepted from 127.0.0.1:52761 #868 (205 connections now open)
Я понятия не имею, что происходит. Если какая-либо другая информация необходима, я могу добавить ее без каких-либо проблем.
спасибо.
