Steps to reproduce:
- Fresh installation of zabbix-agent2 on RedHat 8.10 host
- Use Oracle template by Zabbix agent 2 (Vendor and version: Zabbix, 7.2-1) for multiple (about 90) remote Oracle database instances. The agent cannot be installed on remote hosts with databases, therefore an external host with zabbix-agent2 is used.
- After a few days, all RAM and SWAP is consumed by zabbix-agent2.
Let me just add that test on the same host we have additionally launched the agent gen.1 (also v.7.2.4, works on the standard port 10050, agent2 operates with us on port 20050) to monitor oracla through ODBC and there are no problems with it.
