I’ve just stumbled on this problem, which seems to be quite old and still unresolved.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200319 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? Regards, Stefan -- Stefan Bethke <[email protected]> Fon +49 151 14070811
