Overriding Symfony cache directory causes the composer install processes to never finish

[ricardoee]

Hi,

If I override the cache directory in src/Kernel.php, for example:

    public function getCacheDir(): string
    {
        return \dirname(__DIR__).'/symfony/cache';
    }

Running composer install, causes it to never finish, even after an hour and consuming >13GB RAM. Removing the cache override, it completes the process in under 2 minutes.

What's the issue?

Thanks,
Kevin
