cd /production/ezplatform
php bin/console cache:clear --env=prod && php bin/console cache:pool:clear cache.redis --env=prod
cd /production/ezplatform
php bin/console cache:clear --env=prod && php bin/console cache:pool:clear cache.redis --env=prod

Varnish clean cache

su - LOGIN

cd /production/www/current/docroot
/opt/rh/rh-php73/root/bin/php bin/console cache:clear --no-warmup --env=prod -vvv && /opt/rh/rh-php73/root/bin/php bin/console cache:pool:clear cache.redis --env=prod -vvv

Error PHP

PHP Fatal error:  Uncaught RuntimeException: Failed to start the session

Open the Varnish configuration file: 
/etc/varnish/default.vcl or /etc/varnish/varnish.params

You should see a line similar to the following in your configuration file:

# set the size of the cache in MB
set max_cache_size = 256M;

Increase the cache size:

set max_cache_size = 512M;

Save the configuration file and restart Varnish
