  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Question Can you explain this growing apache memory usage?

Graham Jones

New Pleskian
Each day from 8am to 5pm the apache php-fpm memory usage grows and grows in a sustained way to critical levels before restoring itself to normal. (See screenshot: 2019-11-07_07-41-35.png )

All websites are set to use nginx

The memory usage occurs also when ALL extensions are switched OFF

The memory usage also occurs when ALL cron jobs are switched OFF

Why is apache php-fpm memory becoming critical to the same timetable every day when no websites are apache and when all extensions and cron jobs are off?

Nothing I do seems to change the memory usage
