Hi,
I have an VW eUP and the module is installed via ODB. It is working but I recognized, that the module is crahsing almost every day.
Some times I have to restart it manually (disconnect --> connect).
I see the following error:

Can you help me? Thank you in advance!!
It is crashing in ticker 1.
Do you have any scripts running (javascript, or shell)? If not, then best to post the module summary and we can check.
Note also that this seems wierd:
Your ota_0 image is 3.3.005-3, but the factory image is much newer (3.3.005-842). However, you are running from ota_0?
Hey,
Thanks for your answer!
I updated the firmware and partition now. I hope it was correct :)
I have to wait and see if the OVMS will still crash. I will keep you informed in a few days :)
