Description:
------------
This error began appearing a few days ago after I ran yum update, and recompiled 
PHP, using 

'./configure'  '--prefix=/home/arch120113' '--with-config-file-
path=/home/arch120112/php' '--with-mysqli=mysqlnd' '--with-mysql=mysqlnd' '--with-
pdo-mysql=mysqlnd' '--with-mysql-sock=/var/lib/mysql/mysql.sock' '--enable-bcmath' 
'--enable-calendar' '--enable-exif' '--enable-ftp' '--enable-magic-quotes' '--
enable-mbstring' '--enable-sockets' '--with-bz2' '--with-curl' '--with-gd' '--
enable-gd-native-ttf' '--with-jpeg-dir=/opt' '--with-png-dir=/opt' '--with-
gettext' '--with-imap' '--with-imap-ssl' '--with-kerberos' '--with-mcrypt' '--
with-openssl' '--with-zlib' '--enable-zip' '--enable-fpm' '--with-freetype-
dir=/usr/include/freetype2/'

Now, when I use file_get_contents() on a large file (300KB), not the entire thing 
appears.

Test script:
---------------
https://www.cheatswhiz.com/info.php

<?php

<?php
$expires_offset = 31536000;


header('Content-Type: application/x-javascript; charset=UTF-8');
header('Vary: Accept-Encoding'); // Handle proxies
header('Expires: ' . gmdate( "D, d M Y H:i:s", time() + $expires_offset ) . ' GMT');
header("Cache-Control: public, max-age=$expires_offset");

echo file_get_contents('wp-includes/js/tinymce/wp-tinymce.js');

?>

File it's reading from is https://www.cheatswhiz.com/wp-includes/js/tinymce/wp-tinymce.js

Expected result:
----------------
The entire content of the file is read. 

Actual result:
--------------
Only part of the content is read

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

$expires_offset = 31536000;

header('Expires: ' . gmdate( "D, d M Y H:i:s", time() + $expires_offset ) . ' 
GMT');
header("Cache-Control: public, max-age=$expires_offset");

echo file_get_contents('wp-includes/js/tinymce/wp-tinymce.js');

echo 'test';
?>

where the file, wp-includes/js/tinymce/wp-tinymce.js, contains 
https://www.cheatswhiz.com/wp-includes/js/tinymce/wp-tinymce.js. When that code 
is excuted, only portions of https://www.cheatswhiz.com/wp-
includes/js/tinymce/wp-tinymce.js is read, Also, the echo 'test'; after the 
file_get_contents is not executed.

Look, how should I reproduce when this script only works on your server.
Please provide a self-contained reproduce case.  Eventually check your server 
config, too.

Oops. Seemed to be a nginx proxy issue.
