Basically the transaction was not able to commit. In recent RabbitMQ 
versions transactions a implemented in terms of confirms; this error on 
commit is equivalent to the confirm mechanism having sent nacks.

And the confirm mechanism will only send a nack if a queue crashes. So 
I'm guessing that's what happened - you can check further up the log 
file (sorry, the URL you posted is not responding for me). There were 
several bugs in this area that were fixed in 2.7.1 so you might want to
