[rabbitmq-discuss] Issue deleting Queue

Hi Chris. I think the "+" is likely to be a red herring; you certainly 
should be able to use "+" in a queue name and expect things to work.

Are there any errors in the logs referencing the name of this queue? (I 
should expect there probably are.)

Cheers, Simon
