Tvheadend

Hi

I'm using xbmc and tvheadend as the pvr add-on as frontend and also installed the tvheadend backend.
All of a sudden this error started to show up, no clue why and dont know if any packages has been upgraded.
If i go into system => live tv => general => (add on) tvheadend => enabled sometimes the add on gets enabled but 2 tries out of 3 the system hangs and
needs to be rebooted

All I can find in the /home/xbmc/.xbmc/temp/xbmc.log is:

The seup has been done according to the threads available on the forum
Any ideas? How can I check the connection to the backend? can it be done from prompt? can I get any more logging?
