I've seen these types of errors most commonly when you have another computer on the line with the same IP. That computer gets the message somehow and says 'there is no connection open here with that port/ seq_num, so I'll send an RST'.

I attached a wireshark file at my 1st posting. SYN is ok. GET is not ACK, but there are 2 RSTs! I'm not sure where the GET fails.

The RSTs only happen when the connection is forcibly closed by the application. This can be due to lack of (configured) memory, checksum errors, listen backlog being too small and some more things. You should try to enable LWIP_STATS to see if it is a memory problem (look at the err members of all stats items). If that is not the case, try to enable logging, that should tell you where the problem is.
