--- Comment #30 from Michael Tuexen <tuexen@freebsd.org> ---
(In reply to iron.udjin from comment #29)
In addition, I would also suggest
options TCPPCAP
That would allow us to see the last n packets in/out per endpoint in the ke=
rnel
dump. Just compiling it in does not enable the logging. If we actually want=
 to
do the logging, we need to do something like
sudo syssctl net.inet.tcp.tcp_pcap_packets=3D10
to store the last 10 packets in each direction. We can see if your system c=
an
handle this, since it use mbufs.
