• 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.

Issue mariadb too many open files

Just a heads up:

On your system, eventually the open files limit of mariaDB may not suffice, and most attempts at fixing it will not work, as there is a file
/etc/systemd/system/mariadb.service.d/override.conf
that sets this limit to 8k..

Most sources on the internet says that you should create a new file called limits.conf in that directory with
[Service]
LimitNOFILE=100000

in it.. well, as long as the override.conf is also not updated, the limit will stay the same. ensure to either delete or update this override.conf file as well.
