--Apple-Mail=_31FDEA5D-08EF-49E1-8449-FF2D6285DFDE Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 I=E2=80=99ve just stumbled on this problem, which seems to be quite old = and still unresolved. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D200319 As a quick summary: if you configure CARP on an if_bridge interface, the = CARP state changes will (always/with a high probability) create a = deadlock between CARP and the if_bridge code, leading to the machine = becoming unresponsive. There is a suggested patch, but work on it seems to be very slow: https://reviews.freebsd.org/D3133 I would love to see a fix in 11-stable or 12.0. Is there something I can = do to help move this forward?
