Apparently the channel is not thread-safe, but that is very unlikely
to result in extra messages.

Are you looking on the queue directly through the RabbitMQ management
interface or the rabbit command line tools? Or are you consuming?
Also, are you able to check how many times basicPublish() is called?
Perhaps it's called 1003 times for some reason. Finally, are you
checking the number of messages on the queue before running ab? I
assume you are, but I have to ask :)

Cheers,

Peter
