Hey debandrandy.... not sure if you are still having this issue. I was having the same issue and have found that disabling the Media Browser fixed my issue. I was getting the following errors:
Started XBMC... got URL Error: unable to connect to server
then got the [Errno 11004] getaddrinfo failed error message
and finally got the Error in Artwork Rotation Thread error message
after a few days of looking in the xbmc.logs and seeings these errors relate to XBMB3C addon ...which I did not have... i start to disable and enable addons until I did not receive the error messages any longer. I know, baby/bathwater out the window sort-of troubleshooting. The following addon apparently was causing the problem:
MediaBrowser
If you ARE using the Media Browser, I would suggest reading the thread on troubleshooting and configuration at this link outside the XBMC Community:
http://mediabrowser.tv/community/index.p...to-server/
If you ARE NOT using this addon for whatever reason follow these easy steps:
Go to System ---> Settings ----> Addons ---> Enabled Addons ---> Program Addons ---> MediaBroswer (Right click and select Addon Information or press the C button) ---> Select Disable
At this point my XBMC crashed (looking at my logs later to see why) but I restarted and it is working without any errors so far!
I hope this helps anyone out there...
