Hi, after struggling with this problem for one week I have finally decided to post on the arch list for getting some help. I have a very strange problem with mariadb from the official repos. I run a usual LAMP stack (apache, php-fpm, mariadb) on archlinux. Since one week (or so) I have realized a very strange behavior: One mariadb process stucks on 100 percent CPU usage. I am not able to figure out what's going on. Restarting mariadb fixes the problem for a few hours. Here is a list of a few debug outputs [1]; I have put it in my pastebin because my email client would wrap the text at 80 chars. If you need even more information I can update the paste. The mariadb status page shows about 6,5 queries per second (!) and I don't know where this comes from. I have disabled remote access with "skip-networking" (mysql port is closed) and the PROCESSLIST does only show one process. I thought it might be an DDoS attack on a website but no apache access-log grows unexpectedly. Even after stopping apache mariadb stucks on 100 percent cpu usage. I figured out that there are listed a lot of connections in the output of "show status like 'Con%';". Last hour I even had about 5000 connections but there are no appropriate queries visible in the general log. The general log lists the wordpress queries which are executed when I click on my homepage. Everything looks fine; the cpu usage does not! Do you have any ideas what I can do to figure out what's going on with my mariadb? Thanks in advance! Stefan [1]: http://snippets.sevenbyte.org/8/raw/
