We got this in the log file every 5 seconds(exactly 5 seconds).
What could be the reason? Is this a bug? Fixed?

BTW, we are using spring 3.0.5.

5 seconds is the default delay between connection recovery attempts (setRecoveryInterval).

It means the container lost connection to the broker and cannot reconnect.

What are you using for a ConnectionFactory? What is the DMLC caching level?

The Spring connection factories detect JMX Exceptions (via an ExceptionListener) and reestablish the connections as needed.

Running with DEBUG logging level will add a full stack trace to the 'Connection is Closed' exception.

DEBUG logging should also provide some indication of what is going on during connection recovery.

I didn't set up the DMLC caching level.
Would this lead to any issue?

Not really; it defaults to NONE if there is an external transaction manager, or CACHE_CONSUMER otherwise.

In either case, if the connection is broken, the DMLC gets a connection from the factory. The factory is responsible for creating the connection (or refreshing a dead cached connection).

Thanks.

What if the problem won't reproduce, after I set the logging level to DEBUG?
Does that mean it's a network issue?

That's probably a reasonable assumption, or the broker itself was down.
