Sorry that no-one has been able to advise you, but to ensure this issue
doesn't get forgotten about, could you post it as a bug here please:
https://savannah.nongnu.org/bugs/?func=additem&group=lwip

Have you been able to identify anything which explains why it happens some
times and not others? Is the packet trace any different (e.g. different
order), other than the acks being the expected values when it works?
