The strange thing I'm finding is that by taking the MSS back down to smaller 
values, my lwip system crashes, so I'm wondering whether there is some problem 
with that algorithm on my system.

The window size is still currently 2048.

If I make the MSS 128, 256 or 512, and then send the data stream to it, it 
crashes very quickly. If I make the MSS 1000 it crashes after a while. If I 
make the MSS 1024 it appears to be ok.

I'll continue digging!

Cheers,
Tony
