Magento – PHP Fatal error: Allowed memory size of 805306368 bytes exhausted

I was able to solve this by adding the actual value directly inside the php.ini file and mounting my custom version of it in the container. Apparently the variable PHP_MEMORY_LIMIT is not there when running the cron.

You can see the default php.ini file here https://github.com/mageinferno/docker-magento2-php/blob/master/conf/php.ini

Try following commands:

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento setup:di:compile
php bin/magento cache:flush
php bin/magento cache:clean

//To run command forcefully
php -f bin/magento

//To run command with memory limit 4G
php -d memory_limit=4G bin/magento

//To run command with max memory limit
php -d memory_limit=-1 bin/magento

If you are still facing issue then try following settings:

1. [Magento2-root-folder]/index.php

ini_set('memory_limit',256);

OR

ini_set('memory_limit','-1');

Check current memory_limit value using CLI:

1. php -r "echo ini_get('memory_limit').PHP_EOL;"

2. php -i | grep memory

If the issue are still persist then increase the memory limit (e.g., up to 2048M) in the following places:

1. [Magento2-root-folder]/.user.ini

memory_limit = 768M

2. [Magento2-root-folder]/.htaccess (2 places)

php_value memory_limit 768M

3. [Magento2-root-folder]/pub/.user.ini

memory_limit = 768M

4. [Magento2-root-folder]/pub/.htaccess (2 places)

php_value memory_limit 768M

Issue should be resolved by now, if it is still there then disable your custom module and check again.
