I haven't looked at the source for that application, so can't suggest a
precise fix, but fundamentally those connections are in that state
either because (i) the application has not called close(); or (ii) there
is a bug in lwIP.  The former seems most likely at the moment, and so to
solve the problem you need to know why the application hasn't called
close on those sockets.
