• 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.

Question High CPU usage of mariadbd for long periods of time

mapodec

New Pleskian
Server operating system version
Debian 10.13
Plesk version and microupdate number
18.0.57 #5
I have a problem with the server and a web page.
Since several hours ago, Monitoring360 is detecting that mariadb is using a lot of CPU, being constantly my CPU at 80% according to Monitoring360 (I have an open alert that does not end up closing).

But from Plesk, if I go to Process List, the CPU percentage is 18-20%.

There is a mariadb process that does not finish. In MySQL Process List (Beta) it says that there are several tasks with the status of "Sending data" from a database of a web page.

Does anyone know what is happening and how can I fix it? Attached are several images.
The server I have has good resources (16 vCores and 16 GB RAM).

Thank you very much.
