irregular stop of the function #3

Thank you for your great development work. The GO tool is doing a great job, but it seems to crash after a while. This often takes several days. After ending and restarting the process, it runs again for some time. Have you already noticed similar behavior? Thank you for your support.

Dear @fucide , yes you're right. I have been able to reproduce the error. It looks like it occurs exactly after 4 days of uptime. It looks at first view as if the error occurs in the MQTT module.

I am not sure how to debug this?

Hi @fucide, I've added a workaround for that. The bride will noch extit if the connection is lost. Please keep an eye on the startup.sh script in the bin folder and adapt it to your needs.
