I don't know then - there is no other obvious problem. Just to be sure
you could try printing out a message if there is netbuf_data but it
doesn't match the three GET requests you are expecting.
If that doesn't provide a solution you'll have to dig deeper into lwIP
and find out where your requests are getting dropped. Turning on the
LWIP_DEBUG stuff might help, as could LWIP_STATS code to show if there
is some resource such as packet buffers that is being exhausted and
causing drops.
