Help wanted with debugging

Hello,

I started using the com.athom.dru apps to control my fireplace. This fireplace can be controlled through a gateway using modbus TCP protocol. The app is working, but crashes after a period from 30-60 minutes.

The app was built by an intern from Atom but is not supported.

Debugging the app shows the following:

Can anyone tell me what goes wrong and where I have to look in the code?
The code can be found at: https://github.com/apstemmer/com.athom.dru
