After the installation of micro-update 32 on Plesk Onyx 17.5, server memory usage has significantly increased.
Restart of the PHP-FPM services with the commands below temporary frees memory:
# service php-fpm restart
# service plesk-phpX.X-fpm restart
- where X.X - a PHP version, e.g plesk-php7.1-fpm
Unable to rename a domain in Plesk. The following error message is shown:
PLESK_ERROR: Unable to rename home of sysuser with id=81: Unable to execute usermng: usermng: pam_unix(passwd:xxxx): password changed for limelight usermod: user john.doe is currently used by process 9423
This is a Plesk bug with ID PPPM-7647, which has been fixed in Plesk Onyx 17.5 Update 34.
Since micro-update 32 on Plesk Onyx 17.5, default PHP-FPM settings have been changed.
Install the latest Plesk micro-updates.
As a workaround change PHP-FPM settings for all required service plans:
In Plesk go to Service Plans > Plan Name > PHP Settings.
Scroll down to PHP-FPM settings and change the pm value to ondemand:
Click OK to apply the changes.
Note: Synchronization may take a significant amount of time, if there are a lot of subscriptions assigned to a service plan.
Repeat these steps for all required service plans.
