Symfony 2 computer hungs when I make any request - php

Question

Excuse me for my English.
I have 3 classes: User, Category and Service.
When I do even a simple query to the database for Service, for example findAll(), my computer hangs... At the same time, the query for Category and User are good.
Thank you for your help!

)
);
}
If I modified my function as:
$user = $this->container->get('security.context')->getToken()->getUser();
$user_id = $user->getId();
// var_dump($user_id); ALL IS RIGHT
$em = $this->getDoctrine()->getManager();
$services = $em->getRepository('GeneralAnnuaireBundle:Service')->findAll();
// var_dump($user_id); ALL IS RIGHT
// IF: var_dump($services[0]); COMPUTER HUNGS
// IF: echo count($services); RESPONSE RIGHT
// IF:
return $this->render('GeneralAnnuaireBundle:General:list_services.html.twig',
array('services'=>$services, ));
// SCREEN WHITE

Answer 1

If you print object in browser it get hanged because symphony object contains lots of info. suppose if you have relation with other tables it will have current tables info as well as other related tables info (Schema, Data, Relationship etc.) as well so it might 99% chance to hanged the browser. Better to print "echo count($services)" to check object exists or not.

Answer 2

Try Debug::dump($service) or any variable - you will be able to see the objects (without the proxy)
