As Richard said we have workarounds against this panic and we know what commit opened it up. The commit itself isn't a mistake, though. Instead of committing any of our workarounds we are looking to find the root cause of the panic, a path that would flush socket send buffer but leave sack scoreboard. If you have any clue how reproduce the bug, please share. You mentioned certa= in iperf action/configuration. --=20 You are receiving this mail because: You are the assignee for the bug.=
