我使用mongo驱动程序2.2.2从我的rails应用程序连接。 我注意到我有太多打开的连接。 这是我的测试：正确的方法来关闭连接到mongodb从轨道
@db = Mongo::Client.new('mongodb://user:[email protected]:27017/db')
# nothing to do! only for test!
@db.close
和我同时启动 - Rails应用程序，并在此之后我是创建单个请求我在调试模式下的应用程序和检查的mongod输出的MongoDB
$ rails server
$ mongod

在我的轨输出I见下：
D, [2016-01-30T14:08:30.046532 #12981] DEBUG -- : MONGODB | Adding localhost:27017 to the cluster.
D, [2016-01-30T14:08:30.050656 #12981] DEBUG -- : MONGODB | Adding localhost:27017 to the cluster.
我打算和关闭的mongod，并再次检查导轨输出：
D, [2016-01-30T14:08:50.060270 #12981] DEBUG -- : MONGODB | IOError
D, [2016-01-30T14:09:00.065535 #12981] DEBUG -- : MONGODB | Connection refused - connect(2) for 127.0.0.1:27017

D, [2016-01-30T14:09:30.079056 #12981] DEBUG -- : MONGODB | Broken pipe
最后我的问题：如何真正关闭连接到蒙戈？ 我在做什么错？
