[rabbitmq-discuss] Server error during queue.declare call

Wed Mar 30 15:33:49 BST 2011

Hello,

I've been trying to find info about this in the mailinglist, but I
couldn't find the exact scenario (since most of the seemingly related
issues deal with clusters).

Hopefully someone will recognize the problem and/or can help solve
this issue?

We are using the RabbitMQ 2.2.0 on a single server setup (no cluster)
with a client using the py-amqplib library.

The client sometimes hangs in the queue declare call. And the server
logging contains the following error report:

=ERROR REPORT==== 30-Mar-2011::12:06:44 ===

     {rabbit_channel,handle_cast,2},
     {gen_server2,handle_msg,2},
     {proc_lib,init_p_do_apply,3}]}

Does anyone know if this is a (known) issue with rabbitmq 2.2.0 or py-
amqplib? Or is this a 'new' issue?
