• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service.

  • 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.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Any ideas on this one?
 
Your apache is dieing so oftenly. Are you under a dos-attack during that time? you need to check the webserver logs for a better understanding of the problem.
 
I'm having similar issues as well

Since my update to Plesk 11.0.9, I've noticed similar waves of yo-yo activity for Apache and nginx. The occurrences happen almost exclusively at night. Perhaps it's not a coincidence; but the evenings where the automated backups are being run seen to also be those evenings when the crashes are occurring. Is it a possibly due to some kind of resource battle??
 
The seems to be a strong correlation to the web services restarts and the backups

I was running automated backups on the morning of December 31st. The Watchdog report for that morning shows:

This is a dedicated server with 4GB of physical RAM. Could the extra resources needed by the backups strain the server sufficiently to crash Apache so often? Running CentOS 5.8 and Plesk 11.0.9
