The token timeout that is configured by default is 5 seconds on single site
local networks and 10 seconds when multiple segments are configured. So I'm
not sure why a 2 second communication outage is triggering a membership. 

It could be that it isn't the time involved, but something else. Roughly how
many daemons are running on the lan? Also, when you do the switchover do
both interfaces maintain the same ip address, or do they have separate ip
addresses. Finally, when a switchover occurs do all of the daemons switch to
the new network, or only the one who had a failure.
