Restart device and update existing python file in RPi

Sure @oleorhagen Ill be happy to provide you with any logs or info.

Okay, since you have clarified on my issues are very unfamiliar, I will setup the demo server once again in a new server with sufficient requirements, and if it again occurs then we can take it further with “why” and "how to resolve it " rgt?

Let me setup a new server of Demo version. I hope all these issues wont occur again. Wow, You just mentioned thousand of devices in a demo server? but they have mentioned only 500, How to get few more ?

I would really like to thank you for all these responses, I’m really looking into Mender, I want this to work, Mender looks very interesting !!
