Could be a race-like condition and so not easily triggerable. I may try again later tonight or tomorrow to see if I can re-create it, and m= ay also re-try on my production appliance. FWIW, I use cloned_interfaces to create the bridge interface, too, but I ha= ve learned to list bridge interfaces last in that variable after all member interfaces have been created, and that does seem to avoid some issues that I saw on one of my other appliances. --=20 You are receiving this mail because: You are the assignee for the bug.=
