I tried changing dev.igb.0.iflib.override_ntxqs=3D4096 but to no effect. What did make a difference was to use the rack tcp stack net.inet.tcp.functions_default=3Drack using rack there was next to no packet loss when interrupts were scheduled = onto a single core, obviously not fixing the root cause but is somewhat of a workaround. --=20 You are receiving this mail because: You are the assignee for the bug.=
