Symfony access denied exception on dev environment

My symfony project throws cache write access denied errors seemingly randomly, only in development and testing modes, and when I send multiple requests in a row. Although it doesn’t happen in production, it’s really annoying in development.

I already checked this link, put umask(0000) in the beginning of my bin/console and public/index.php files, and still the same problem.

Here’s a example of a regular output that I get from the project.

Acces is denied exception

I’m using apache over Wamp64, regular installation. Does anyone have this same problem? Is there a cure for this permissions disease?
