Restarting openhab3 container produces errors


recently, restarting the OH3 container produces the following error message:

2022-11-02 02:47:55.421 [ERROR] [ore.common.registry.AbstractRegistry] - Cannot inform the listener "org.openhab.core.thing.internal.ChannelLinkNotifier@430348d9" about the "ADDED" event: Invalid BigDecimal value: 
java.lang.NumberFormatException: Invalid BigDecimal value

Then I have to reboot the NAS for oh3 to work.

Can someone tell me what this message means?

You probably tried this already, but last time I got weird errors (some months ago: access rights errors upon startup, last week: very poor system performance) I emptied /userdata/tmp/ and /userdata/cache/ and everything worked great afterwards. Maybe worth a try.

Thank you for your answer, I had already tried that. I have since determined that the cause was an incorrect installation of a specific addon. Now I can start the container again without any error messages.
