     Windows NT operating systems. It uses a single control process
     which launches a single child process which in turn creates

+        Child: Encountered too many AcceptEx faults accepting client connections.<br />
+        winnt_mpm: falling back to 'AcceptFilter none'.
+    </example>
+
+    <p>The MPM falls back to a safer implementation, but some client requests
+    were not processed correctly.  In order to avoid this error, use
+    <directive module="core">AcceptFilter</directive> with accept filter 
+    <code>none</code>.  <em>In Apache httpd 2.0 and 2.2,
+    <directive>Win32DisableAcceptEx</directive> was used for this purpose.</em></p>
