Lots of errors on server log

Hi,
Very sorry for cross-posting, I already posted this http://forums.slimdevices.com/showthread.php?107004-Dynamic-Playlists-plugin-not-showing-my-own-playlists-on-RPi.
I'm trying to have a fully functional LMS on RPi and I have some problems: my own dynamic playlists are not working, I'm trying to use MusicIP on raspberry with some problems too and it's sometimes very slow. After some reflection, I think have too many strange errors in the server log, so maybe it's the source of my problems, and not the plugins.
I attach the server.log.

Thanks a lot
Antonio
