Symfony2 app_dev.php only error 500 Premature end of script

Question

I has problem with Symfony2. All work fine, and one day... start the problems ...

When i open a page, i get error 500. The server return this error, not Symfony. If i refresh, I display display the page without error. But when i open a new page (new url, same site), the error come again.

I tried to reload apache. I tried remove all in cache and logs. My console file, app.php file, app_dev.php file have umask(0000) uncommented.

This is the last line of symfony2 logs when i have the error :

The apache error log :

[Fri Sep 04 11:24:49 2015] [error] [client my.ip.here] Premature end of script headers: app_dev.php

The problem does not exist in prod, when i use app.php

The syslog does not have line about this. I don't have problem on other website on the same server. I don't have hard drive space problem.

Anyone have an idea ? thx

The app_dev.php file :

<?php


use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Debug\Debug;


// If you don't want to setup permissions the proper way, just uncomment the following PHP line
// read http://symfony.com/doc/current/book/installation.html#configuration-and-setup for more information
umask(0000);

// This check prevents access to debug front controllers that are deployed by accident to production servers.
// Feel free to remove this, extend it, or make something more sophisticated.
if (isset($_SERVER['HTTP_CLIENT_IP'])
    || isset($_SERVER['HTTP_X_FORWARDED_FOR'])
    || !in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', 'xxx.xxx.xxx.xxx'))
) {
    header('HTTP/1.0 403 Forbidden');
    exit($_SERVER['REMOTE_ADDR'].' : You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}

$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
Debug::enable();

require_once __DIR__.'/../app/AppKernel.php';

$kernel = new AppKernel('dev', true);
$kernel->loadClassCache();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

For apache configuration, it's isp config configuration, i just added this for this website :

Apache directive :

DocumentRoot /var/www/clients/client2/web56/web/symfony/web/
FcgidMaxRequestLen 20000000

php.ini :

apc.shm_size = 256M
realpath_cache_size = 4096k
realpath_cache_ttl=7200
session.auto_start = 0
xdebug.remote_autostart=0
xdebug.remote_enable=0
xdebug.profiler_enable=0

In config_dev.yml, if I remove firephp and chromephp from monolog configuration, the problem is solved. I don't think it's good solution, anyone have an other idea ?

Answer 1

I have commented firephp and chromephp in config_dev.yml :

imports:
    - { resource: config.yml }

framework:
    router:
        resource: "%kernel.root_dir%/config/routing_dev.yml"
        strict_requirements: true
    profiler: { only_exceptions: false }

web_profiler:
    toolbar: true
    intercept_redirects: false

monolog:
    handlers:
        main:
            type:  stream
            path:  "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug
#        firephp:
#            type:  firephp
#            level: info
#        chromephp:
#            type:  chromephp
#            level: info

assetic:
    use_controller: true
