Hi Simon,

Ok, I understand (pcb)->recv is set to null in close().
I updated to CVS head.
I looked at the tcp.h history and it seems that this bug has been around since 
ages...

I'll try to reproduce my bug and see how lwip behaves with the fix.

It's not easy, because it can happen only after several hours.

of the http POST content, so I consider the connection closed.
I added more debug info in the response.
It may be an lwip bug or misconfiguration (recvmbox size ?)
