Mongodb连接不在nodejstesting中closures
因此，我有一套黄瓜testing，并在BeforeFeatures部分创build连接到同一台服务器上的2个数据库，我已经将池设置为2，所以我可以看到当我连接4个连接发生（2个数据库有2个池）。
然后最后我closures数据库，如下所示：
var closeDatabase = function(callback) { db1.close(function(){ db2.close(function(){ console.log("DONE"); callback(); }); }); };
现在这个被调用，我看到控制台输出，进程closures，所以两个数据库连接应该closures。 但是，如果我看一下mongodb日志：

所以最后，尽pipe2个连接已经结束，但是似乎将4个连接中的3个连接活动起来。 这就是说，如果我们看看端口，它似乎激活6个端口，即使它只有4个连接。
那么这是常见的？ 我应该担心还是我做错了什么？ 这是一个问题的全部原因是因为当我尝试使用连接时，我得到的错误：
MongoError: server localhost:27017 sockets closed
所以当我尝试使用连接时，为什么看起来过度分配和轰炸，我感到有点困惑。
所以错误是正确的，它是closures连接，然后使用它们，由于他们的方式控制台输出发生在窗户上，他们并不总是100％在正确的顺序。 原来黄瓜在一个地方默默无闻地爆炸，在这里有一个敲门的效果。
