Unifi-Controller MongoDB crash on startup with Signal 7 (Bus Error)

LSIO Discussion Container Support

Hi, i’m deploying the Unifi-Controller to my RPi 4 4GB via docker-compose.
The docker-compose.yml is this:

---
version: "2.1"
services:
  unifi-controller:
    image: linuxserver/unifi-controller:LTS
    container_name: unifi-controller
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Rome
    volumes:
      - /media/ssd/my-docker/unifi/config:/config
    ports:
      - 3478:3478/udp
      - 10001:10001/udp
      - 8080:8080
      - 8443:8443
      - 6789:6789
    restart: unless-stopped
    networks:
      - traefik_default
    
networks:
  traefik_default:
    external:
      name: traefik_default

After the deployment, the docker log say this:

      _         ()

Seems mondodb crash on startup.
Same behaviour using label “latest” for the unifi image version.

Could you try mapping the /config folder to /home/usernamehere/unifi as a test? I think it might be a permissions issue.

Hi j0nnymoe,
sorry for delay, i was on summer holydays :slight_smile: !
i changed the mapping of /config to /home/pi/unifi-test (i leaved the creation of the folder test-unifi to docker-compose), but i’ve got the same error from mongodb.
For test i even changed permission to 777 of the folder test-unifi, same issue.

Here the mongodb.log latest lines:
