Chris,

I upgraded the backup from 2.3-REL to 2.3.1-DEVELOPMENT (amd64), built on Thu May 12 \
23:47:16 CDT 2016. It started working as expected as soon as that one booted after \
the upgrade.

On this backup node, capturing the ff02::12 I'm now *ONLY* seeing those from the \
master.

And I do not suffer anymore (well I hope I'm not speaking too soon, but it is stable \
for >1 hour now) of the weird effect of some packets choosing to go to the backup \
instead of the master.

Has something been changed/fixed in the current snapshots which would explain this or \
I'm just running by chance, I do not know.  I'll try to understand by reviewing \
redmine for bug fixes and changes.
