  <p>Following is my httpd.conf:</p>
  
  <pre><code>ServerTokens OS
  ServerRoot "/etc/httpd"
  PidFile run/httpd.pid
  Timeout 295
  KeepAlive Off
  MaxKeepAliveRequests 100
  KeepAliveTimeout 15
  WLMaxWebSocketClients 1024
  
  # prefork MPM
  &lt;IfModule prefork.c&gt;
  StartServers      25
  MinSpareServers   50
  MaxSpareServers   200
  ServerLimit      2048
  MaxClients       2048
  MaxRequestsPerChild  2000
  #WLMaxWebSocketClients 1024
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>So as per above config I have set WebSocket connection limit to 1024, but it reached the limit at 30-40 connections.</p>
