Unable to update web-statistics in Plesk: PHP Fatal error: Allowed memory size of X bytes exhausted

Symptoms

• The web-statistics calculation does not work: The values at Tools & Settings > Traffic Usage by Domains (under Statistics) are not updated.

• When manually recalculating the statistics for a domain, the operation fails with the following error message:

  # /usr/local/psa/admin/sbin/statistics –calculate-one –domain-name=example.com
  PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 62390354 bytes) in /usr/local/psa/admin/plib/Service/Agent/Transport/Local/Exec.php on line 240

Cause

PHP memory limit is exceeded.

Resolution

1. Connect to the Plesk server via SSH.

2. Increase memory_limit in PHP configuration of Plesk:

   2.1. Open the file /usr/local/psa/admin/conf/php.ini in a text editor. In this example, we are using the vi editor:

   # vi /usr/local/psa/admin/conf/php.ini

   2.2. Navigate to the line memory_limit and increase the value to 1024M.

   2.3. Save the changes and close the file.

3. Restart the sw-cp-server service to apply the changes:

   # service sw-cp-server restart

4. Recalculate statistics for all domains with the command:

   # /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f ExecuteWebStatistics
