[rabbitmq-discuss] Null pointer exception while dispaching to dynamic(temporary) queues

[Emile Joubert]

Hi Kotresh,

I don't see any Rabbit library calls in the stacktrace - are you running 
out of Rabbit connections? Perhaps someone on the list with Mule 
experience can help you better, but it looks like you need to ensure 
that completed requests return their connections to the pool or you 
might need a larger pool.
