My best guess is that this is a multi-threading problem.  You could
check this by either moving all lwIP socket related code into one
thread, and using some inter-thread communication mechanism to separate
the data flow out if necessary into separate threads, or put a mutex
around the socket accesses so that only one of your threads can be
active in lwIP at one time.

I would like it if lwIP supported access from separate threads using
separate sockets (note, we're not going to support a single socket
accessed from multiple threads, or even handing a socket over from one
thread (e.g. a listening thread) to another).  So if there are problems
in this area we should take a look.
