async scope is not working in Clustering in mule 3.4.2

Question

async scope is not working in Clustering in mule 3.4.2. we are getting below exception.

Message               : Interrupted while queueing event for "SEDA Stage Main_Flow.async1". Message payload is of type: ConfirmReceiveMessageResponse
Code                  : MULE_ERROR--2

    + 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

After removing the async scope we are able to test the application. Could please help us how to make the application works with async in cluster env?

Are you using the Community version or the Enterprise version ? — Naveen Raj, Oct 26 '15 at 14:03

Can you post your config? Are you using a flow-ref in you async block by any chance? — Ryan Carter, Oct 26 '15 at 14:29

If the flow ref is using an async processing strategy it will try and persist the event in a cluster I believe. And your object is not Serializable.

You can make com.sample.client.ReceiveMessageResponse implement java.io.Serializable if you want the message to be persisted.

Or you can try forcing the flow that you are flow-ref'ing processingStrategy="synchronous" maybe.

where message will be persisted whether it will be persisted in java heap area (or) physical VM(filesystem) (or) anywhere else? . – Gopi Oct 27 '15 at 09:46
