title: MongoDB and MongoHQ Live Logs
body: <p>I'm connecting to MongoDB using Mongoose in my node application. </p>
  
  <p>I can see the below console.log logged once:</p>
  
  <pre><code>mongoose.connect(myURL)
  var db = mongoose.connection
  db.on('error', console.error.bind(console, 'connection error'))
  db.once('open', function callback() { 
      console.log('Opening MongoDB Connection')
  })
  </code></pre>
  
  <p>But in the MongoHQ live logs, I'm seeing 5 new connections open / close every-time I open or close the connection from the node(express) app. Why is this so and is it an issue with the code?</p>
  
  <p>Also I have two candidates in the Live Log, candidate 0 and 13, where 13 is the one I'm actually connecting to. What is the candidate 0 there for? Is it just like a default for all MongoDBs in MongoHQ or it shouldn't be there?</p>
