| Description |
|
I deployed a Zabbix server using the Docker image zabbix-server-pgsql:7.0.6-alpine. The problem is that my configuration cache usage exceeds 90%. I reconfigured the Zabbix container by increasing the CacheSize parameter from 20 GB to 30 GB. However, when I restarted the Zabbix server container, it got stuck at the process: I also checked the server resource usage. During startup, the Zabbix server consumed almost all available RAM, leaving only around 100 MB, which made the server unresponsive. I then rolled back the CacheSize parameter to 20 GB, but after restarting, the Zabbix server container was still stuck and continued to consume all available RAM. I don’t understand how the configuration cache works and why Zabbix is consuming almost all of the RAM. If the RAM usage should match the configured CacheSize, it shouldn’t be using all the available memory. When the Zabbix server container is stopped, there’s still around 40 GB of free RAM. Is there any workaround to solve this issue? |

Please share Zabbix server log file with enabled debug level 4. After 20 minutes from startup. |

Seems, it happened when I initiate stop zabbix-server container. Because the server became unresponsive since lack of RAM. |

Or maybe because the other zabbix-server is taking over, becasuse that server is unresponsive. |
