Symptoms
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)
Cause
Memory limit is exceeded by Plesk PHP back-end. This may happen if an object, over which the operation is performed, has a complex structure.
Resolution
For Plesk on Linux
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
/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1 && sed -i '/memory_limit/cmemory_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
/opt/psa/bin/sw-engine-pleskrun /opt/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1 && sed -i '/memory_limit/cmemory_limit = 512M' /usr/local/psa/admin/conf/php.ini
Restart the Plesk management service:
Start PowerShell and run the commands one by one:
PS
import-module WebAdministration
net stop "Plesk PopPass Service"
net stop "Plesk Management Service"
net start "Plesk Management Service"
net start "Plesk PopPass Service"
Restart-WebAppPool PleskControlPanel
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.
