Indefinite wait on RabbitMQ channel close

Hi Everyone,

I am facing one strange issue and need your help.

I started facing an issue with the RabbitMQ Java library. When I am trying to close the channel, sometimes it is indefinitely waiting for closing channel and blocking my thread.

The only recent change that we have done in the system is RabbitMQ server upgrade to 3.7.x.

Now, The server version is 3.7.X. The client library version that I am using is 3.3.x. Will there be any compatibility issues b/w 3.3.x(client library) and 3.7.x(rabbitmq server) ? Do I need to upgrade my client Java Library. If so, to which version do I need to upgrade ?

Thank You,

Giridhar
