title: iOS: DNSServiceGetAddrInfo failed
body: <p>Everything in my app uses either Alamofire or MDWamp.</p>
  
  <p>When the app is on for a longer period of time I get a crazy amount of these errors:</p>
  
  <pre><code>&lt;Error&gt;: tcp_connection_host_start 7181 DNSServiceGetAddrInfo failed: -65537
  &lt;Warning&gt;: dnssd_clientstub deliver_request: socketpair failed 24 (Too many open files)
  &lt;Error&gt;: tcp_connection_host_start 7182 DNSServiceGetAddrInfo failed: -65537
  &lt;Warning&gt;: dnssd_clientstub deliver_request: socketpair failed 24 (Too many open files)
  &lt;Error&gt;: tcp_connection_host_start 7182 DNSServiceGetAddrInfo failed: -65537
  &lt;Warning&gt;: dnssd_clientstub deliver_request: socketpair failed 24 (Too many open files)
  &lt;Error&gt;: tcp_connection_host_start 7183 DNSServiceGetAddrInfo failed: -65537
  &lt;Warning&gt;: dnssd_clientstub deliver_request: socketpair failed 24 (Too many open files)
  &lt;Error&gt;: tcp_connection_host_start 7183 DNSServiceGetAddrInfo failed: -65537
  </code></pre>
  
  <p>I'm struggling to reproduce this and I can't find any information elsewhere..
  Any hint or idea would be appreciated.</p>
