Hi, I have exactly the same problem explained below (except with FreeBSD 8.2RC3). I lost a lot of packets on the carp interface.
I tested with a point-to-point attachment and there is no problem... Now that I know that the problem must comes from the switch, how can I solve it ? Is there a workaround on the FreeBSD side ? May my switch be misconfigured or bugged (I have tested with HP Procurve switches 1800 and 2910al) ? I'd greatly appreciate your help to solve this issue.
