title: Apache Optimization: Frequent "Oops Not Found" error for my website
body: <p><strong>The problem:</strong>
  I a have a small web application (PHP/MySQL) that a client of mine uses. Often they have about 10-15 users in the same network that use the application. We have been noticing frequent "Oops not found" being displayed on their browsers. </p>
  
  <p><strong>The diagnosis</strong>
  I am assuming it's Apache settings, as I have not seen this issue replicated on other networks. It's probably because of simultaneous connections being issued from the same IP. </p>
  
  <p>I have tried enabling mpm in apache using by adding this code httpd.conf </p>
  
  <pre><code>&lt;IfModule mpm_worker_module&gt;
      ServerLimit             250
      StartServers             10
      MinSpareThreads          75
      MaxSpareThreads         250 
      ThreadLimit              64
      ThreadsPerChild          32
      MaxClients             8000
      MaxRequestsPerChild   10000
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>But I am still getting the same issue. Any suggestions? </p>
