Answering to my own question.

Indeed it was a PHP error - memory limit exhousted. It turned out when I binded to php cgi process via strace. Nginx did not return 500 status code. It did not even view fatal errors and log them (despite error_reporting = On with E_ALL).

I don`t know why. I will ask another question about that.

Which version of symfony you are using? The scenario looks more like a php error caused by mismatched function parameter or non existent function call. -Run your application with debug enabled in your app_dev.php. - add E_RECOVERABLE_ERROR in ErrorHandler.php handleFatal() funtion where error type is checked. Generally a mismatched function parameter throws a php error of type E_RECOVERABLE_ERROR and is not handled properly on symfony. Once this is done run your page again. Hopefully the error will throw up on your page. Hope this helps

Well, in symfony2 it's easy to return like:

return new Response(null, 200);

wich does exactly what you say it does. Are you sure you are returning content from symfony2?
