It sounds like somehow the state is becoming corrupted. This isn't a familiar problem. I do remember that some of the older pre-packaged versions of lwIP that were included with Xilinux or Altera products (can't remember which) were not well ported and so had bugs that limited their usefulness, but I don't recall anything that sounds like you describe. If you can see the problem IP address with LWIP_DEBUG in the terminal then I would start adding more tracing - the ICMP code is quite small - and see if you can work out when the address gets changed from the "good" value to the "bad" value.
