I have zabbix-server 5.02 installed on CentOS7 x64 and MySQL-server (mysql 5.7.30) on different server with CentOS7.
Gradually, the zabbix-server runs out of RAM. I noticed that this is proportional to how the number of read requests and row locks on the mysql-server. Is there a known issue with this version of Zabbix?
If you need to provide config files or some kind of logs, please inform.
Below are 2 screenshots of mysql-server monitoring.
