Error on starting Jupnp

Setup, Configuration and Use Runtime
,
1

when starting the JUPnP bundle manually (or on startup for that matter) the following error is produced…Not sure if its an issue, but i dont like errors

openhab> start 156
openhab> [Fatal Error] :1:3: The markup in the document preceding the root element must be well-formed.

Also, but im still investigating, i think its also filling up the heap space. at least 5 times every minute contact is attempted as per the following… Im still doing some analysis but im pretty sure something is going on. if i stop the bundle then memory and cpu is pretty consistent, with it running memory grows continuously until heap errors are seen in openhab.

I think, you have a server in your network (IP 192.168.10.47, Port 49153) which needs Authentification. As openHAB has no credentials, Authentification fails forever.

yup, i sort of guessed that, proprietary STB so cant modify it.

ok, just to add some more, upnp is causing heap errors, not sure if its because of the constant polling as above but after a few hours seem to always get

Looks as if you’d better report this at https://github.com/jupnp/jupnp/issues.
