I see that too. I don't think the unit actually crashes, but it can be disconcerting.
Also, I'm trying to compare the digital out into my DAC to the internal DAC but the digital out can't stay locked (I think that's it... my receiver keeps reseting like it used to between PCM and MP3).
I wonder if this is could be related to the "crunchy distortion" I reported last night with my own SB2. I can't confirm it, but it very definitely sounds like the firmware in the box is starving the DAC when it has to handle the sustained, high speed burst of incoming traffic that fills up the playback buffer with raw PCM data. If the DAC is indeed being intermittently starved, perhaps this is killing the clock on the S/P-DIF output and making it difficult for your external DAC to maintain lock.
Does the problem happen on all files, or only those transcoded to raw, high speed PCM? And does it persist through the entire track, or does it only happen at the beginning? The "crunchy distortion" I notice on my SB2 only occurs on raw, high speed PCM, and only until the buffer fills. When that happens and the server backs off to its "maintenance" speed of about 1.4 megabits/sec, the distortion goes away.
It just occurred to me that I could try forcing the Ethernet down to 10 megabits/sec and see if the problem still occurs. If it's indeed due to DAC starvation from lack of proper CPU real-time management, this might work around the problem by limiting the peak speed of the buffer-fill burst to only 10 Mb/s.
