I've had similar issues. The daemon is just trying to map your ports automatically on your router. Sometimes this works, sometimes it doesn't. It's a harmless message. You can try disabling uPnP on your router to see if that gets rid of the message.
'UPnP device' error when running monerod
SOLVED: Was running bitmonero on 32-bit Ubuntu. Fixed when changing OS to 64 bit.
EDIT: Initial post indicated this was a UPnP issue, which it likely is not. I've updated the post below to what I now think is the problem.
I am trying to set up a Monero node (compiled from source Sept 7th). The blockchain seems to have been only partially synced. In my bitmonerod log this is repeating non-stop:
IN EDIT: Update log file excerpt below after running at log level 3.

bitmonerod then silently exits after this, and restarted by supervisor. Nothing else shows up in the logs.
I should have mentioned that my monero deamon is continuously restarted and no longer syncing. This is an excerpt from supervisord.log:

Ad infinitum.
I assumed this had something to do with the messages in the bitmonerod (in my first post). Will toy around with the router though when I get a chance...
Are you using a fairly recent build from github? I would try to delete the blockchain data files and try to re-sync.
Also, you may need to hop on #monero-dev or go the the Monero support thread on bitcointalk. I'm not well versed with linux.
I compiled from the source code on GitHub.
I tried deleting the blockchain data. It then re-synced. I'm not sure up to what point but now, a day later, the deamon still exits with the same errors in the logs as above.
