Sorry about thati, I think it was a missfire and didn't contain
any new information at all.

Ok, as I mentioned in an earlier post, there is no code that I am aware
of that forces the active to send all its connection data over to the
standby node. Which is basically what you need. Perhaps Karl has
information about such a patch. Perhaops it out there and I am just
missing it. But I suspect that he was just talking about the code that
was merged into 2.6 ages ago, and you are already running.
If you are worried about connections being dropped when your master
plays reboot games you have two options.
1) Find, make, or sweektalk someone else into making a patch that
allows a syncd to request the other side to send all its data,
and hopefully notify the requesting side when it is done.
This will still be a bit racy, as very new connections on
the active node might not have been synchronised when a failover
occurs. But this isn't any worse than the situation when an
active node goes down, and should help your problem.
2) Make it so when a failover occurs, the node that takes over becomes
the master, and stays the master until it fails. If you use
heartbeat set auto_failback=off
