Hello,
I have the same behaviour in release 2.4 - 1, this started after clearing the cache
sudo systemctl stop openhab2
sudo openhab-cli clean-cache
sudo reboot
and my error log
2019-08-23 09:20:36.958 [ERROR] [e.internal.WriterInterceptorExecutor] - MessageBodyWriter not found for media type=text/event-stream, type=class org.glassfish.jersey.media.sse.OutboundEvent, genericType=class org.glassfish.jersey.media.sse.OutboundEvent.
This error logs periodically when the Browser Basic UI sitemaps is open and only once at the Android openHAB app when starting lunching it.
I posted this because it may help to repeat or debug this behaviour. Now I will try to solve it with recommendations.
bye
NOTE: ERROR gone after rebooting once…
Reproducing the ERROR log:
sudo systemctl stop openhab2
sudo openhab-cli clean-cache
sudo reboot
ERROR log returned
sudo reboot
ERROR log gone…
conclusion: in my version OH 2.4 the ERROR log described before and the continuous disconnects of basic UI sitemaps started after “openhab-cli clean-cache” and was solved with a single “reboot”.
