title: Node.js server randomly throws EAI_AGAIN
body: <p>My Node.js server sometimes throws an EAI_AGAIN error, and I don't know why. I have multiple, completly different Node apps running on my Linux server and when this error throws, it mostly does on all apps the same time. The error occurrs not regularly, this week once and 2-3 times in the last month. </p>
  
  <p>On this <a href="http://linux.die.net/man/3/getaddrinfo" rel="nofollow">Linux manpage</a>, I can see that EAI_AGAIN means the following:</p>
  
  <blockquote>
    <p>The name server returned a temporary failure indication. Try again later.</p>
  </blockquote>
  
  <p>Is there anything wrong on my Linux server or in my Node apps? Or should I just ignore this error? Maybe it's an error that sometimes just occurrs like a timeout and I can't do anything against it?</p>
