I've gotten to the root of the problem - it has to do with the fact
that the second
rabbit broker is doing a redirect, i.e, from
/var/log/rabbitmq/rabbit.log I see:
INFO REPORT==== 14-Mar-2009::00:18:55 ===
connection <0.16842.0> redirecting to
So it looks like I need to solve this problem by either using my
or they need to handle redirects better.
With py amqplib, I can put "insist=True" inside of "amqp.Connection",
and I don't see
the failure anymore ( socket.gaierror: (8, 'nodename nor servname
provided, or not known'),
but I'm stilling wondering if the clients should handle the redirect
With txAMQP, I have not yet seen if you can even pass a "insist=True"
anywhere. The txAMQP also
does not follow the redirect (as far as I can see), it just sort of
'hangs', but I'm probably
just using the client wrong ...I'm going to do more investigating.
Maybe the authors of either python client lib are around, and they
could set me straight
on this use case :-)
