I did NOT any tuning or settings.
I have downloaded mysqltuner but according to it, everything is OK, I can post log here ?

 

To find out what is using the memory, run this command:

Code:

ps -e --format=pid,vsz,comm | sort -n -k 2

You can read man pages of ps and sort to find out what those command do with these arguments.
Useful information on how to troubleshoot your system can be found using Internet Search engines, for example with

Code:

linux which process is using memory

PS You still have not shown output of uptime command.

 

Hi Till,
Which MariaDB cnf file is responsible for tuning server?
