Can it be some problems in PPOS input path? Some data that may hang PPOS in

I doubt an input issue would consistently show up at 12 hours on a regular basis?

How about the other questions? 

1. Is it 12 hours after you boot your device or 12 hours after the connection is started [test by starting the connection an hour after booting the device]? 
   
2. How many characters have been transmitted and received when the failure occurs?
3. How does the failure manifest itself?  Does your device actually crash or just stop communicating?
   

You said it happens sooner if you do larger transfers??  Any other clues with regards to that??

What more can you tell us about your usage?
