enable some more lwip debugging output and saw that at some point pbuf fails to
allocate memory on receiving a packet.
Yeah, it's clear from the pcap that lwip stops
processing packets from the host.
It looks like you need debug statements in memp_malloc
and memp_free rather than packet content.

FWIW - In the txt file from the original post, there is
UDP traffic from 192.168.9.1 to 192.168.9.255
which is being seen by lwip. They don't show up
in the pcap.
