      When I run the command to bring it up, everything starts apart from the Zabbix server (backend), so I can access the web ui, see the DB is good, on the face of it anyway.

      The error within the container doesn't really give me much to go on, I wondered if someone here may shed some light at least in the direction of where to look.

      Full error:

      Attached

       

      Zabbix server variables;
      **

      ZBX_STARTPOLLERS=10
ZBX_STARTPINGERS=50
ZBX_CACHESIZE=2G
ZBX_HISTORYCACHESIZE=1G
ZBX_VALUECACHESIZE=2G
ZBX_TIMEOUT=30

       

      Steps to reproduce:

      1. start docker compose
      2. watch it burn

      Result:
      See Full error
      Expected:
      Compose will completely start and server will start gathering data

      Any help appreciated.
