The versions of both lwIP and FreeRTOS you are using are pretty old. At 
least lwIP has numerous bugs fixed since then.

Using a socket full duplex (read from one thread, write from another 
thread) is not supported in lwIP 1.4.0. You'll need at least 2.0.x for 
that, but only recent git master versions support aborting waiting read 
threads on close.
