The problem

each instance restart leads to the following log errors. the instance is green and seems to run.

edit: after downgrade to 6.6.1 i get the same error with this version. such log error never exists in all old log files until 9th december with some shelly 6.6.1 restarts.

iobroker.current.log (in debug mode!)

Redis? Maybe not enough memory left?

[Diginix]

No redis and memory usage of proxmox VM: 86.90% (6.95 GiB of 8.00 GiB)
I can ignore this as long as all is working fine. But as I understand there is a try-catch missing and with this it would be better?

[klein0r]

This is an issue with the states DB. What should happen if the getState / setState failed? It's not just catching an exception. What happens afterwards if the value is missing.

[Diginix]

I have tested some relay switches r/w from iobroker and in Shelly app. All was updated on both sides in realtime.
Seems to be not related to the latest version if it happens also with 6.6.1. So, maybe it is a temporary local thing on my machine.
