Cause of the Allowed Memory Size Bytes Exhausted Error
The cause of the error “allowed memory size of bytes exhausted” is obvious i.e. it’s related to shortage of memory. The error occurs if you try to use more RAM resources than what you have specified in the php.ini file through “memory_limit”.
Running a Large Dataset
It can occur when you are running an operation using a large dataset. While Magento is a highly powerful platform, it consumes significant server resources. Therefore, memory issues are quite common. For example, when simultaneously updating thousands of product descriptions or importing/exporting a large number of products into the database, you may see ‘allowed memory size of bytes exhausted’ error.
Poor Code Optimisation
Poorly written code can also result in high memory consumption. Therefore, always choose a reliable Magento development company when you require custom development work. They have the experience and skills necessary to take on any project, regardless of its complexity.
Using Too Many Extensions
Secondly, Magento 2 is a highly customisable platform. With extensions and custom Magento development, you can tailor each aspect to your requirements. However, using a large number of extensions and customisations can cause you to consume large amounts of memory. It is quite common to experience the allowed memory size of bytes exhausted in such a situation.
Cache or Indexing Issues
Solution to Allowed Memory Size of Bytes Exhausted Error
Remember, out of memory errors are quite common but equally easy to fix.
Method 1: Edit the php.ini File
All you need to do is increase the memory limit in the php.ini file and this will resolve the ‘allowed memory size of bytes exhausted’ error. It is the default configuration file that is used to control upload sizes, file timeouts and resource limits. This is what you have to do to resolve the error.
- Locate php.ini file. This will usually be etc/php.ini.
- Find the parameter memory_limt =128M
- Increase the limit to 2G (2048 MB)
Method 2: Use the Command Line
You can also increase the memory limit using the following commands.
php -d memory_limit=1G bin/magento setup:di:compile
php -d memory_limit=1G bin/magento setup:static-content:deploy
You can change 1G to whatever limit you want. This will surely resolve the error allowed memory size of bytes exhausted in Magento 2.
Method 3: Edit the index.php in Magento Root
Open the index.php file and then add:
ini_set('memory_limit', '2G');
You can change 2G to 4G or any other number as per your requirements.
