Hawkbit server doesn't work after few hours online

Question

I have an hawkbit server behind a traefik proxy running on docker-compose

mysql:
  image: "mysql:latest"
  environment:
    MYSQL_DATABASE: "hawkbit"
    MYSQL_ALLOW_EMPTY_PASSWORD: "true"
  restart: always
  ports:
      - "3306:3306"
  volumes:
    mysql-db-data:/var/lib/mysql
  labels:
    NAME: "mysql"
  networks:
    hawkbit-network

hawkbit:
  image: "hawkbit/hawkbit-update-server:latest-mysql"
  environment:
      - 'SPRING_DATASOURCE_URL=jdbc:mariadb://mysql:3306/hawkbit'
      - 'SPRING_RABBITMQ_HOST=rabbitmq'
      - 'SPRING_RABBITMQ_USERNAME=guest'
      - 'SPRING_RABBITMQ_PASSWORD=guest'
      - 'SPRING_DATASOURCE_USERNAME=root'
  volumes:
    artifactrepo:/artifactrepo
  restart: always
  ports:
      - "8080:8080"
  depends_on:
    mysql
  labels:
    NAME: "hawkbit"
    traefik.enable: true
    traefik.http.routers.hawkbit.rule: Host(`hawkbit.domain`)
    traefik.http.routers.hawkbit.entrypoints: hawkbit
    traefik.docker.network: docker-files_traefik-network
    traefik.http.services.hawkbit.loadbalancer.server.port: 8080
  networks:
    hawkbit-network
    traefik-network


volumes:
  mysql-db-data:
    driver: local
  artifactrepo:
    driver: local


networks:
  traefik-network:
  hawkbit-network:

Right after the building of the docker compose, everything works fine, I have access to the UI, can connect, save parameters.

But after few hours, hawkbit seems to lost the connection to the database

SQL State  : 42000
Error Code : 1049

When I look with docker ps, I see the uptime of mysql container have few hours less than the hawkbit one.

So it's seems to be a volume problems, as mysql container has been rebooted and can't find data.

It's confirmed when I try to restart mysql container, hawkbit one, and both without result, but removing mysql volume and restart both works and it's up for few jours before crashing again.

I don't see where I made a mistake on volume declaration, can it be another problem?

Thanks
