However, if I make this single change (kern.ipc.maxsockbuf=3D614400000, as per Calomel's tuning gui= de) then the problem crops up very soon after on the iperf3 server side. When it occurs, both sb_acc and sb_ccc are equal (typically around 3.4-billion). --=20 You are receiving this mail because: You are the assignee for the bug.=
