Operations in Plesk fail: Allowed memory size of X bytes exhausted (tried to allocate Y bytes)

By RadioHost.gr on 13 Νοεμβρίου 2023

An operation fails in Plesk with a blank page or one of the following error messages in Plesk:

PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 16384 bytes) in /path/to/plesk/file.php on line 228

Out of memory (allocated 23855104) (tried to allocate 12975879 bytes) (Abstract.php:41)

Connect to the Plesk server via SSH.
Open the Plesk PHP configuration file php.ini in a text editor. In this example, we are using the vi editor:
# vi /usr/local/psa/admin/conf/php.ini
Increase the memory_limit value to 512M:
memory_limit = 512M
Save the changes and close the file.
Restart the Plesk management service:
# service sw-engine restart && service sw-cp-server restart
Redo the previously failed operation. If it fails with the same error, increase the memory_limit limit to a greater value and restart the services.
To prevent the changes from being reverted during Plesk update, replace the following line in /etc/cron.daily/50plesk-daily using a text editor:
- on CentOS/RHEL-based distributions
  /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1
  
  with
  
  /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1 && sed -i ‘/memory_limit/c\memory_limit = 512M’ /usr/local/psa/admin/conf/php.ini
- on Debian/Ubuntu-based distributions
  /opt/psa/bin/sw-engine-pleskrun /opt/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1
  
  with
  
  /opt/psa/bin/sw-engine-pleskrun /opt/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1 && sed -i ‘/memory_limit/c\memory_limit = 512M’ /usr/local/psa/admin/conf/php.ini
