IPTables.  Though, if it was working and it's available via ip addr
list, it should still be working.

When this happens, does the IP still appear in 'ip addr list' ?  What
about running 'clustat' -- is the service started, or did it perhaps
fail?

Ok, there was/is a bug with e1000 in bonding configurations if you have
4+ of the cards in the system.  That's what I was looking for.  Since
your configuration has none of the above criteria, it's unlikely to be
that problem.
