If you think this is not the case, please provide traces for the investigat= ion. Also if it is reproducible, better provide tcpdump traces together with some kernel traces like TCP blackhole log, or SIFTR (I prefer https://github.com/ccfbsd/siftr2), or even a packetdrill script. --=20 You are receiving this mail because: You are the assignee for the bug.=
