NodeRed Stops Flow – General

Dear All,

I installed two times nodeRed (using dockers). On installation was on a test PI 3 and the other on productive PI 4. Both are same image with Bullseye.

On my test PI 3, everything went fine and is running since two weeks without any interruption.
After this successful test, I also installed it on my second PI. But unfortunately, after each 4-5 minutes, the flow stops. Even without any interaction, the flow stops (suddenly).

Even with logging on trace level, I couldn’t find any additional information about it.

Do you have any hints for me?
