Hmm, I think it is not related to maintaining connection state, but somehow to a bad interaction with the Baystacks. perhaps not sending gratuitous ARPs, or perhaps some problem with how multicast is used. There seemed to be plenty of warnings about multicast traffic for load sharing.

Ideally I'd find someone who already had this problem and has a solution or has seen something like it with other switches and has a suggestion for this clustered situation.

Thanks.
