yes, this is a problem that cropped up at the time when I think 2.5.0 released. First, the rest API moved. The configuration is in .cfg file or somewhere. Hang on and I’ll try to find the threads involved. There isn’t anything wrong with your zwave, OpenHAB can’t find a certain addon and is trying to reload the misconfigured addon over and over resulting in your issue. I will try to find the threads describing the fix so check back in a few minutes or search restarting every 60 seconds
check this thread
Here is a quote from Bruce that describes the problem:
If you are running openHAB 2.5 or newer and upgraded, you likely have an invalid addon in your config that restarts all addons every 6- seconds trying to load the invalid one. A common culprit is restdocs since its location moved. Check the addons.config (not addons,cfg) file down in the userdata tree.
