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

Tue May 17 09:58:04 BST 2011

Hi,

We are using rabbitmq1.8 with mule for multithreading. In multi threading its creating separate connection for each request and after 24 requests reaching max pool size and throwing below exception.
May I know how we can handle this issue ? This issue is only with dynamic queues ? How we can use single connector for multiple requests. It may be related to Mule issue if you have any idea please let me know thanks in advance.
