• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

I read that Plesk supports a maximum of 900 users per server? But you could do a tweak to increase that?
 
This article:

I was more wanting to know if anyone has done this and some example settings.
This is the Obsidian article but it's basically the same:

 
Has anyone done this? Recompile Apache to handle more than 900 users? What about a LiteSpeed server? Would that make a difference and handle more?
 
There has been a similar request in the Plesk Facebook group recently. I can only say that we had never recompiled Apache, yet it serves >1,500 domains on some systems. The only thing that has always been necessary is to set the max number of files that can be opened in the Apache files and the system. Other issues have not been seen here for many years. I am not sure whether this is a CentOS specific thing, though.
