Additional info:
Comment 2 Matthew Farrellee 2011-11-28 14:34:51 UTC 
Can this be reproduced with qpid-tool instead of cumin?
Comment 3 Stanislav Graf 2011-12-05 07:19:11 UTC 
I am not able to reproduce this error with qpid-tool or qpid-config. We need probably more info what is going on inside of cumin to find another way to reproduce.
Comment 5 Stanislav Graf 2011-12-05 16:20:35 UTC 
I was able to reproduce this one using qpid-route:

# qpid-route link add <dest-broker> <src-broker>

# qpid-route link list
