Currently the streaming just stops after a undefined period of time, when the stream is stopped in VLC and (re-)opened agian, the busy animation becomes active on the TV. This takes about 15 mins. Then it recovers and the TV zaps (when running from 2 tuners) to the channel that was streaming and the streaming on the PC resumes as well. The following messages are taken from "/var/log/messages" and this seems to be why the stream stops.

The time on the Dreambox LCD is 09:37, the Dreambox is always the same 15mins = 900secs busy. I didn't found any triggers for this. When it recovers at 09:51 no messages appear in the "/var/log/messages" log. After 2 mins the following appears in the log so thats just some normal messages.
 
  Jul 27 09:53:54 dm7020hd user.info kernel: [ 5039.699000] bcm4506: signal_strength -196.68dbm

During the busy period of the Dreambox, the OpenWebif, remote control nor buttons are not responding. You can still login to the Dreambox using SSH. I did some tracing of the engina2 application, but the only messages comming out are;
 
  [eFilePushThreadRecorder] Warning: All write buffers busy
  [eDVBRecordFileThread] cancelling
  [eDVBRecordStreamThread] failed to cancel, killing all waiting IO
  [eDVBRecordFileThread] poll: aio_return returned failure: Value too large for defined data type
  [eDVBRecordFileThread] poll: aio_return returned failure: Value too large for defined data type
  [eDVBRecordFileThread] poll: aio_return returned failure: Value too large for defined data type
  [eDVBRecordFileThread] Waiting for I/O to complete
 
These messages repeat themselfs, but when the enigma2 application is BUSY no messages are being outputed. But i think this is releated to the CCcam share slowly or not responding sometimes.  
 
My Dreambox has two S2 tuners, and there is no difference in behaviour between running the stream from the same tuner (one tunner active (ZAP)), or running from active 2 tuners with different channels.
 
I think that XBMC vuplus add-on has a more aggresive connection strategy to which results in sometimes hanging up the Dreambox completly. 
 
 
 
Any ideas how to find and/or solve the problem ?

See our topic regarding active support for dmm boxes

dmm builds automaticly as other brands but if things fail it fails and we do not fix it anymore ourselves or someone has to deliver us à patch
