Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP --
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php
If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
I believe this may be a duplicate of https://bugs.php.net/bug.php?id=69316 which is
fixed, as the test script provided for this bug shows an issue on PHP 5.6.2 but not in PHP 5.6.7
However the version you are reporting it on, 5.4.41; that version is only receiving security updates
now due to the PHP support lifecycle - http://php.net/supported-versions.php
Please re-open this, or open a new issue, if you can reproduce this issue on a up-to-date version of
PHP.

Description:
------------
When PHP-FPM with Apache, using multi_curl with verbose mode and CURLOPT_STDERR sending to a stream
(fopen), if you close the stream (fclose) before removing the handle from multi_curl, you will an
500 error
I also have the "Memory map". I can provide it if useful.
Using the same script with a cron job works without any error

Test script:
---------------
// Initialisation
$mh = curl_multi_init();
// cURL handle
$ch = curl_init();
$fp = fopen(__DIR__ . '/verbose.log', 'a+');
curl_setopt_array($ch, array(
CURLOPT_URL => 'https://www.google.com',
CURLOPT_SSL_VERIFYPEER => true,
CURLOPT_VERBOSE => true,
CURLOPT_STDERR => $fp
));
curl_multi_add_handle($mh, $ch);
// Close stderr handle
fclose($fp);
// Remove handle
curl_multi_remove_handle($mh, $ch);
Expected result:
----------------
Plain PHP: I'm expecting an php error or exception to be thrown instead of working
PHP-FPM: I'm expecting an php error or exception to be thrown instead of an apache error 500
Actual result:
--------------
- apache: (104)Connection reset by peer: [client 92.90.16.5:3482] FastCGI: failed to read from
backend server
- php log: no error
- php-fpm log:
