https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D286631 --- Comment #2 from JY <yjaeyong@gmail.com> --- Created attachment 261049 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D261049&action= =3Dedit pcap for congestion window drop after successful recovery I attached a pcap. We are not actually using the FreeBSD OS. We are using user-space TCP stack with fstack and cherry-picked the releases from your 14.3 to our software.= In our system, unfortunately we don't have black-box logging. If you let me know specific part you want logging, I can rerun the test col= lect the logs. I will also share the logs that I added in tcp_sack_doack, which gives me c= lue for this suspection. --=20 You are receiving this mail because: You are the assignee for the bug.=
