https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264257 --- 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 kernel 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=10 to store the last 10 packets in each direction. We can see if your system can handle this, since it use mbufs. -- You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.
