<h3>概述</h3>
<p>This Multi-Processing Module (MPM) is the default for BeOS. It uses
a single control process which creates threads to handle requests.</p>
</div>
<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="directive-section"><h2><a name="MaxRequestsPerThread" id="MaxRequestsPerThread">MaxRequestsPerThread</a> <a name="maxrequestsperthread" id="maxrequestsperthread">指令</a></h2>
<table border="1" cellpadding="0" cellspacing="0" bordercolor="#AAAAAA" class="directive">
<tr><th><a href="directive-dict.html#Description">说明</a></th><td>Limit on the number of requests that an individual thread
will handle during its life</td></tr>
<tr><th><a href="directive-dict.html#Syntax">语法</a></th><td><code>MaxRequestsPerThread <var>number</var></code></td></tr>
<tr><th><a href="directive-dict.html#Default">默认值</a></th><td><code>MaxRequestsPerThread 0</code></td></tr>
<tr><th><a href="directive-dict.html#Context">作用域</a></th><td>server config</td></tr>

<tr><th><a href="directive-dict.html#Module">模块</a></th><td>beos</td></tr>
</table>
<p><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>注意：</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>
