I have a strange problem where raw API LwIP (2.0.2) seems to work most of the time but appears to randomly stop.  So I put wireshark up and looked at the messages between LwIP and the server it was talking to.


From the description of your program, it sounds like your problem could well be that you're violating lwIP's threading requirements.
Have you read the documentation on how lwIP must be used (e.g. http://www.nongnu.org/lwip/2_0_x/pitfalls.html)?
