Hello @3mstecnologia!

You can configure CacheSize using environment variables! If you go to Docker Hub for the zabbix-server (https://hub.docker.com/r/zabbix/zabbix-server-pgsql) they will list the extra environment variables!
Means you can do something like:

My example:

zabbixServer:
  enabled: true
#
#.... (hid other parameters)
# 
  extraEnv: 
    - name: ZBX_CACHESIZE
      value: "8M"
    - name: ZBX_VALUECACHESIZE
      value: "8M"

Change the values ​​according to your needs.

Can you test?
