<p>The <code class="directive">MaxRequestsPerThread</code> directive sets
the limit on the number of requests that an individual server thread
will handle. After <code class="directive">MaxRequestsPerThread</code>
requests, the thread will die. If <code class="directive">MaxRequestsPerThread</code> is <code>0</code>, then the thread
will never expire.</p>
<p>Setting <code class="directive">MaxRequestsPerThread</code> to a
non-zero limit has two beneficial effects:</p>
<ul>
<li>it limits the amount of memory that a thread can consume
by (accidental) memory leakage;</li>
<li>by giving threads a finite lifetime, it helps reduce
the number of threads when the server load reduces.</li>
</ul>
<div class="note"><h3>Note:</h3>
<p>For <code class="directive"><a href="../mod/core.html#keepalive">KeepAlive</a></code> requests, only
the first request is counted towards this limit. In effect, it
changes the behavior to limit the number of <em>connections</em>
per thread.</p>
