[rabbitmq-discuss] rabbitmq erlang client connection issue

[joe lee]

Hi,

I just checked out rabbitmq client, using rabbitmq-server 1.2.0 with
cotton-0.2.3.tar.gz which supports hessian 2.0.

I was following this blog tutorial:
http://hopper.squarespace.com/blog/2008/1/12/introducing-the-erlang-amqp-client.htmland
for whatever reason, rabbitmq-server is not accepting the client
connection.

My rabbitmq-server uses all default values for user "guest" and password
"guest".  I haven't made any changes.  I started the rabbitmq server with
/usr/sbin/rabbitmq-server and aborted the erlang node to stop the rabbitmq
server.  This causes problem during restart.  I get an error such as mnesia
table timeout.  More likely this is occuring during mnesia trying to recover
the tables.

Back to erlang client connection problem:
