https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289240 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |markj@FreeBSD.org Status|New |Open --- Comment #2 from Mark Johnston <markj@FreeBSD.org> --- I'm seeing this failure too. The problem is that the recv buffer ends up with sb_ccc > sb_hiwat, and the last recv from the test does not consume enough bytes to bring sb_ccc below hiwat, so nl_process_received_one() does not process anything in the snd buffer. I'm not sure if it's a kernel bug or not. The test could just read from the socket until FIONREAD reports that the number of available bytes is small enough, but I have no idea how this stuff is supposed to work. It would be nice to fix this though.. -- You are receiving this mail because: You are on the CC list for the bug.home | help
