title: What is "error in __connection_block_invoke_2: Connection interrupted" in iOS?
body: <p>I am tried to make iOS Application using <code>AFNetworking</code> in <code>UITableView</code>. TableView loads 20 datas like Twitter's timeline.</p>
  
  <p>When it loads over 80 datas, Xcode shows spending about 70MB memory and console shows </p>
  
  <pre><code>"Received memory warning."
  </code></pre>
  
  <p>And</p>
  
  <pre><code>**"error in __connection_block_invoke_2: Connection interrupted".**
  </code></pre>
  
  <p>What is this and How do I treat this error?</p>
