Every now and again a Razberry hangs with this message:

etc, for every message in the queue

Basically, it fails to deliver any messagei

Doing a 'sudo reboot' does not help. Only a power cycle (by removing the USB power) helps.

My questions are:
1. What is this error, and why does it happen every X weeks.
2. Can I recover without unplugging the device from power?

I can fairly easy detect these messages in the queue using your great API, so I know when it goes wrong, but want to take actioni.

So in a situation now where after 'sudo reboot'ing the device does not work (Web GUI won't even come up again, but I can SSH into the raspberry which seems to work just fine, just not the Razberry). Looked in the z-way-server-log and found a list of messages like this:

Your RaZberry seems to die... Can you paste the line with RECEIVED string?

Hi, i have the same problem since a few days.
how can i check if the razberry card is out of order ?

Thanks,

Christophe

Does it recover after full reboot? Does it work stable/unstable?

This is what it aswers me (in the progress column) whatever the command i try (for example"(Re)include device").
I tried to re-install the software, soft reboot, hard reboot (power off and on) and it's always the same thing. When i try to include a device, the red led shines but no device can be included.
