Node-RED crashes randomly

Hi!
I have multiple instances from Node-RED on different devices. On one big one for a lot of smart home stuff I have crashes almost every day. It is running in a docker container. A lot of other container are up for months on the device. I have no idea how to start the search why its crashing. For the beginning here is the console log from docker - any tipps how to start the search of the reason?

Are you sure its crashing, look at this logfile it looks more to me the the nr instance is restarted for some reason.
What's in the entrypoint.sh on line 14?

I think it is crashing. If I do a restart on the container it looks like that:

I think the entrypoint comes from this setting:

But I have no idea what this is, furthermore I'd never set this setting. It is set automatically whith the default docker file / image layers:

8 ENTRYPOINT ["docker-entrypoint.sh"]
