title: Node.js server stops responding
body: <p>I am working on node.js HTTPS requests. I have done enough research and checked all things as well but still I think I am missing something. 
  What I want to achieve is, when someone sends HTTPS GET request to my URL, I have to send them one file in response so they can download. Everything works fine, I have implemented "FS", "HTTPS", and it writes in proper manner as well, but when I send bulk traffic on my URL after every 1000 requests on an average 40 requests gets failed. </p>
  
  <p>I am not sure why is this happening, I have set this as well:</p>
  
  <pre><code>var https = require('https');
  https.globalAgent.maxSockets = Infinity;
  </code></pre>
  
  <p>Can anyone please help me to understand and resolve issue? 
  Thanks in advance!</p>
