Ok, thank you. We use rabbit 1.8.0 with AMQP 0-9-1 specification. The
frame "Open-Ok" of Channel.open message has probably changed (I havent
checked the details). But the channels are functionnal.

We have seen thanks to wireshark, that the ipvadm machine that
loadbalances the 2 rabbit nodes was sending to the application server
machines TCP RST if the connections are not used for a 10 mn period
(we must see that with our op team).
In that case, the java socket that publish the message cannot know
that the connection will be reset by the VIP server. I guess also that
it must occur between connection heartbeats.

We had understood :)

Thanks again for your answer.
