<h3>Summary</h3>
<p>This Multi-Processing Module (MPM) is the default for the
Windows NT operating systems. It uses a single control process
which launches a single child process which in turn creates
threads to handle requests</p>
<p>Capacity is configured using the
<code class="directive"><a href="/mod/mpm_common.html#threadsperchild">ThreadsPerChild</a></code> directive,
which sets the maximum number of concurrent client connections.</p>
<p>By default, this MPM uses advanced Windows APIs for accepting
new client connections. In some configurations, third-party products
may interfere with this implementation, with the following messages
written to the web server log:</p>
<div class="example"><p><code>
Child: Encountered too many AcceptEx faults accepting client connections.<br />
winnt_mpm: falling back to 'AcceptFilter none'.
</code></p></div>
<p>The MPM falls back to a safer implementation, but some client requests
were not processed correctly. In order to avoid this error, use
<code class="directive"><a href="/mod/core.html#acceptfilter">AcceptFilter</a></code> with accept filter
<code>none</code>. <em>In Apache httpd 2.0 and 2.2,
<code class="directive">Win32DisableAcceptEx</code> was used for this purpose.</em></p>
