title: Apache 502 Error - Server Hang up
body: <p>I am using EC2 instance (t2 Medium) with Apache, MySQL and PHP. I am getting on regular basis 502(Server Hangup) error. Trying to find a solution from week but didn't able to resolve it. </p>
  
  <p>I am using <code>mpm_prefork</code> with server config.</p>
  
  <pre><code>&lt;IfModule mpm_prefork_module&gt;
  
      StartServers             15
  
      MinSpareServers          15
  
      MaxSpareServers          25
  
      MaxRequestWorkers        200
  
      MaxConnectionsPerChild   1000
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>Also not able to see 502 status code in access &amp; error logs.</p>
  
  <p>Any suggestion will be very helpful.</p>
