<name>MaxRequestsPerThread</name>
<description>Limit on the number of requests that an individual thread
will handle during its life</description>
<syntax>MaxRequestsPerThread <var>number</var></syntax>
<default>MaxRequestsPerThread 0</default>
<contextlist><context>server config</context></contextlist>

<usage>
    <p>The <directive>MaxRequestsPerThread</directive> directive sets
    the limit on the number of requests that an individual server thread
    will handle. After <directive>MaxRequestsPerThread</directive>
    requests, the thread will die. If <directive
    >MaxRequestsPerThread</directive> is <code>0</code>, then the thread
    will never expire.</p>

    <p>Setting <directive>MaxRequestsPerThread</directive> 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>

    <note><title>Note:</title>
      <p>For <directive module="core">KeepAlive</directive> 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>
