Geoserver-MariaDB

I have a Geoserver 2.17 installed on Centos using Tomcat. Geoserver obtains data from MariaDB. Mariadb memory usage keeps increases until geoserver or mariadb crashes. Crash occur usually after a week. See attached image.

Centos RAM 6GB
MariaDB 10.3.30

Deliverable:
Optimum configuration of Geoserver and MariaDB ram usage to prevent constant increase and crash.
