Steps to reproduce:
Upgrade Zabbix server from version 6.0.25 to 6.0.31.
The version of the monitored host has not been changed.
Result:
After the upgrade, the usage rate of the History write cache started to increase around 9:45, and the History write cache became full.
The usage rate of the History write cache started to rise from around 9:45 the next day, so we expanded the History write cache. After that, there was no sign that the usage rate of History write cache would decrease, so I downgraded Zabbix from 6.0.31 to 6.0.25.
After the downgrade, the history write cache stabilizes at a value close to 0%, suggesting that the issue is likely due to the upgrade.
We have already upgraded the development environment Zabbix to version 6.0.31, and the same issue has not occurred.
Expected:
After upgrading Zabbix, we expect the usage rate of the history write cache to stabilize at a value close to 0% without continuing to increase.
To address the vulnerability "CVE-2024-22120," we are considering upgrading Zabbix to version 6.0.28 or later.
