Steps to reproduce:
How to use zabbix.
- Enable encryption by certificate in Host settings.
- Memory usage will increase over time.
How to use the script.
- Clone zabbix repository. (git clone --depth 1 https://github.com/zabbix/zabbix.git && cd zabbix)
- Place the attached script.rb in the root directory of the repository. (cp <path to script.rb> .)
- Run script.rb. (ruby script.rb)
Result:
See screenshot for how to use zabbix.
- The server restarts zabbix-agent2 every day around 6 am.
See the log below for how to use the script.
You can see that the memory usage increases with the number of calls made by zabbix_get.

Since tls_description is called from Client#String, the following commit seems to be the cause.
This is why it has been occurring since version 6.0.19.
