How to correctly invalidate cache on production for Symfony2 application?

You missed env parameter: app/console cache:clear --env=prod --no-debug

i believe you can try app/console cache:clear --no-warmup

To clear the cache and instantly access the data my fix is

sudo app/console cache:clear --env=prod --no-warmup --no-debug

using this command turns off debug, and doesn't have a warmup time before the data is accessible again
