[rabbitmq-discuss] 500 Internal server error while consuming with 2.1.0 management plugin

Thu Sep 16 10:50:45 BST 2010

Thanks for the bug report. Now I know where my automated tests are 
inadequate :)

If I'm correct this should happen a few seconds after a new client (not 
the first one) comes on line, and it's transient. Does that match what 
you're seeing?

Cheers, Simon
