We're using a XNUT-100, and have noticed it will run a simple serial<->ethernet 
bridge app for just over 2hours before "going away"...  one time, when left, it 
appeared to come back on its own, but I have been unable to verify or repeat that.

I had suspicions that more accurate timing might show it stopping around the 
2hours 11minutes mark, which happens to be 131,072ms.  This is, in fact, quite 
close to what our testing showed, which made me suspect it was a counter 
somewhere overflowing.

Also, our network has a constant stream of ~280byte ethernet frames, which is 
the music-on-hold for our voice-over-ethernet telephone system.  Further testing 
has shown the box runs for (at least) over a day if this traffic is not present.
