This is a common problem.  It means that the the pcb lists have become
corrupted.  This is almost always due to not using lwIP correctly with
different threads.  You need to ensure that there is only a single
thread accessing lwIP at any one time.  Can you give examples of how
you're using lwIP (e.g. which API, OS, port, etc; how your application
is structured and how your driver passes received packets up to lwIP)?

Thanks
