Answer 1

Caused by: com.rabbitmq.client.impl.UnknownChannelException: Unknown channel number 23364

We found an issue when channels are churned a lot; you need to increase the channel cache size in the rabbit caching connection factory.

See this answer for a work-around.

I opened a JIRA issue so that the next version of Spring XD will expose this setting by in servers.yml so you don't have to override the bus configuration file.
