https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264257 --- 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. --=20 You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.=
