In that case abandon the debug logs, but if possible keep logging error 
messages and assertion failures.  Try and get a wireshark capture that 
corresponds to the failure if you think it is related to particular traffic.  
My guess is that it's a timing dependent crash that is triggered by receiving a 
few packets quickly, so wireshark might not help us much, so if it's difficult 
then don't worry.  The most useful way to solve the problem might be to try and 
work out how to provoke it and so make it more reproducible.
