invalidate() does not clear session in symfony2 controller

I want to destroy a session in one of my Symfony2 controllers and am using following code:

$this->get('session')->invalidate();

But it appears that this does not in fact get rid of the session data and I have to manually remove session variables like so:

$session->remove('viewed');
$session->remove('name');

Is there a way I can troubleshoot why invalidate() does not clear the session?

P.S. If I do:

session_start();
session_destroy();

It works, so it's not a server/php/browser issue.

It does work as follows:

$request->getSession()->invalidate(1);

As invalidate leaves the current session untouched if you are not providing any parameter you have to set the lifetime on 1 (one second)

If you're using a custom session name start the session with that name first before invalidating it to successfully clear it.

$session = $this->get('session');

$session->setName('session_name');
$session->start();
$session->invalidate();

Make sure that you have a session to invalidate in your script.

$session->start();      // Start the session...
$session->invalidate(); // ...then invalidate

Try:

$this->get('session')->clear();

If that doesn't work you could use this:

$session = $this->get('session');
$ses_vars = $session->all();
foreach ($ses_vars as $key => $value) {
    $session->remove($key);
}
