Q:

Symfony cache:clear php.CRITICAL: Fatal error: Allowed memory size

I am encoutering the following error with Symfony when trying to
php app/console cache:clear

or 
php app/console cache:warmup

Fatal error: Allowed memory size of xxx bytes exhausted.
I already set memory limit to very large size 1024M, 2048M.
I removed all twig templates from my project
I unactivated vendors bundles leaving only FOSUSer and FOSRestBundle.
I am unable to track from where this error comes from.
Any idea?
Thanks
I get the following error 

A:

In the end, it was that little piece of code that was the problem:
# config.yml
...   
twig:     
    paths:
            "%kernel.root_dir%": app

Thanks guys for confirming me that it was Twig the problem.
