Hi,
You need to modify memory in php-fpm configuration
You must increased the Memory Limit in/opt/bitnami/apps/magento/conf/php-fpm/php-settings.conf
editing the line:
php_value[memory_limit]=256M
with the value:
php_value[memory_limit]=2G
You have also to modify the file /opt/bitnami/php/etc/php.ini
editting the line:
memory_limit=2G
with the value
memory_limit=2G
Then restart the servers performing:
/opt/bitnami/ctlscript.sh restart
Best regards,
Silvio Fernández
