Something strange about msqld memory usage
I run my VPS on CentOS 7. I just setup LAMP (with mariadb), phpMyAdmin and PPTP for VPN server. Just pure setup. I didn't create another php file or database.
I run "top" command and watch some time. I just realize that mysqld process running every 25 seconds, shows up only 3 seconds and then disappear. This happens every 25 seconds and looks like below:
What is the reason of that? Is it a some kind of memory leak? Is there any way to optimize mysql to avoid this problem?
Thanks for your help
P.s. That would be great if we can add images to questions.
