      MARIADB_INSTALLTENTHREE='y'
      
      
      MARCH_TARGETNATIVE='n'

      NGINXBACKUP='n'
      
      

    Because I run xenforo, they suggest using PHP 8.2 this meant that I had to move to the 130.00beta branch of centminmod. Prior to this my system was running fine with relatively low CPU usage. Once I moved over to the beta branch almost immediately my CPU usage went to over 100% on both cores and has stayed there.


    The only change was moving to the beta branch

    Here are some of the stats from the VPS back end (linode)

    I tried rolling different versions of the PHP to see if that was the cause, however its the same issue.

    It looks like its mariadb that is somehow causing this from using htop, so imagine it has to do with the version change

    Any thoughts on what may be the issue here or how to go about bring this back under control?

    Ok so ran an upgrade of mariadb to 10.4 this seems to have had a positive effect on CPU consumption by mariadb. I am going to watch for a while and then maybe just up us all the way to 10.x because this could just be a version issue

    Ok spoke too soon it looks like we are still bouncing high CPU usage. Next move is I may move back to a backup or see if I can rollback to 124.00Stable

    Rolled back to a server backup from yesterday which has 124.00stable on it. Restored the database from today and load is sitting at about a 7% average rather than near on 200%

    Nginx 1.27.x
    MariaDB 10.x/11.4+
    Centmin Mod 130.00beta01 switch doesn't touch MariaDB version, so would be unrelated most likely. Moving from 124.00stable to 130.00beta01 is about the centmin.sh menu code so if you haven't ran the menu for options 4 or 5 for Nginx and php-fpm upgrades etc, then nothing has changed. But you said you ran menu option 5 for PHP 8.2 upgrade.

    See https://community.centminmod.com/threads/how-to-troubleshoot-high-cpu-load-issues.22483/ for tools to investigate high CPU load.

    For MariaDB you can see what queries are running on command line that maybe cpu intensive
