title: Network Error (tcp_error) A communication error occurred: ""
body: <p>Last days, I deployed a PHP app(ZF2) on a EC2 instance(Ubuntu Server 12.04).</p>
  
  <p>I installed classic packages for a LAMP environment.</p>
  
  <p>I defined my vhost then I test my website.</p>
  
  <p>The website worked fine and sometimes I have the error : </p>
  
  <p><strong>Network Error (tcp_error)  A communication error occurred: ""</strong> </p>
  
  <p>I have no error. I checked Apache logs, PHP logs, etc but I found nothing why I have this error something.</p>
