[rabbitmq-discuss] RabbitMQ Client 2.7.1 Memory Leak?

Sat Jul 14 15:35:26 BST 2012

Hi,

We are using RabbitMQ 2.7.1 Java Client and Server 2.7.1.
While we were running load tests using our clients we observed that our
memory has reached to 2GB.

Below is the snapshot of heap analysis.

We are closing the channels properly using channel.close().
Could someone suggest what could be the problem for this memory leak. Do
the later versions of RabbitMQ solve this problem?
