<h3><a name="error.sendfile" id="error.sendfile">Invalid argument:
|
|
core_output_filter: writing data to the network</a></h3>
|
|
|
|
<p>Apache uses the <code>sendfile</code> syscall on platforms
|
|
where it is available in order to speed sending of responses.
|
|
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>
