Hello,
I am struggling with my OpenHAB 2.5.12 migration running in a Docker container - from Raspberry Pi 3 Plus to Raspberry Pi 4. The OpenHAB container is communicating with a Mosquitto container for MQTT.
Current state:
OpenHAB runs “ok” on the Raspberry Pi 3 Plus, but due to memory limits (only 1 GB RAM) and a notorious startup issue I decided to invest in a Raspberry Pi 4 with 4 GB of memory.
The current startup issue leads to an OpenHAB container boot loop which is settled after 20 to 40 minutes with all webinterfaces being available and rules being processed. It seems that if the Raspberry Pi 3 Plus is cooler, a successful startup process is accelerated.
The logs do not show any clues for me in the moment when the container fails:
openhab.log:

Future state:
OpenHAB 2.5.12 running on the new Raspberry Pi 4 with identical configuration.
Tasks done:
- Full backup of the persistent docker folders openhab_addons, openhab_config and openhab_userdata from Raspberry Pi 3 Plus
- Fresh Raspberry Pi 4 install including docker and updated to the latest versions
- Creation of identical folder structure on the Raspberry Pi 4 and recursive copy of the three folders from the backup
- sudo chown -R 9001:9001 openhab_* to have correct permissions set
- Start of Docker container using docker-compose:
OpenHAB.yml:
version: '2.2'

Observations:
The Raspberry 4 also runs into an OpenHAB container boot loop (like Raspberry Pi 3 Plus). After again 30+ minutes the webinterfaces went online but all my things are missing in the PaperUI. I verified the file org.eclipse.smarthome.core.thing.Thing.json located in Docker/OpenHAB/openhab_userdata/jsondb and to my surprise it is empty. I stopped the OpenHAB container, copied the file a 2nd time and started the container again. Again, after 30+ minutes the webinterfaces show up but the things are missing again. Also, the previously copied .json file (864 KB) is now 0 KB again! It seems that somehow the original file is being discarded and replaced by an empty one after several unsuccessful startups.
What can you suggest to analyze and fix this problem. Currently I am out of ideas.
Thanks in advance!
