title: Random SSL log "AH01998: Connection closed to child with abortive shutdown" apache
body: <p>I am getting SSL handshake failures randomly when number of concurrent users increases. Though the number is not that big, with only 100 users or so SSL handshake keeps failing randomly.</p>
  <p>I have set the <code>LogLevel</code> to <strong>debug</strong>, but seemingly it doesn't tell me anything more significant apart from <strong>AH01998: Connection closed to child with abortive shutdown</strong>.</p>
  <p>Usage of the memory is also not that high when the handshake failure happens. I am using apache V2.4.6 on CentOS 7, with mpm prefork.</p>
  <p>Two things I would like to know:</p>
  <ol>
  <li><p>does the log entry for &quot;abortive shutdown&quot; has anything to do with SSL handshake failure?</p>
  </li>
  <li><p>How can I debug it and understand what is causing the issue?</p>
  </li>
  </ol>
