We had the exact same problem. And it turned out that
there wasn't anything wrong with LwIP. In our case the Problem was with the Ethernet Controller
itself. It basically stopped all services after its internal receive ringbuffers
were completely saturated. The status was written to a fault register and
could be read by our driver. Then all that was neccessary was a reset of the PHY/FEC
to make it work again (and reporting the error to higher levels).
With this change, our Setup survives a Packetstorm
of several million packets at 10000kbps without any crash.
