+ <p>Apache uses the <code>sendfile</code> syscall on platforms

+ Unfortunately, on some systems, Apache will detect the presence of
+ <code>sendfile</code> at compile-time, even when it does not work
+ properly. This happens most frequently when using network or
+ other non-standard file-system.</p>
+
+ <p>Symptoms of this problem include the above message in the error
+ log and zero-length responses to non-zero-sized files. The
+ problem generally occurs only for static files, since dynamic
+ content usually does not make use of <code>sendfile</code>.</p>
+
+ <p>To fix this problem, simply use the <code class="directive"><a href="../mod/core.html#enablesendfile">EnableSendfile</a></code> directive to disable
+ <code>sendfile</code> for all or part of your server. Also see
+ the <code class="directive"><a href="../mod/core.html#enablemmap">EnableMMAP</a></code>, which can
+ help with similar problems.</p>
