AMQ212054: Destination address=... is blocked. If the system is configured to block make sure you consume messages on this configuration

Question

I am using Artemis 2.7.0.redhat-00056 (AMQ 5.11 I think)

One of the camel routes was set up ages ago. It sends XML on a queue, which is then handled in a bean.

So it uses JMS style code:

    producer = session.createProducer(destination);
    producer.setDeliveryMode(DeliveryMode.PERSISTENT);
    ...
    TextMessage message = session.createTextMessage(xStream.toXML(corMessage));
    producer.send(message);

This works 99% of the time, but today we started getting:

    Caused by: java.lang.IndexOutOfBoundsException: Error reading in simpleString, length=6702096 is greater than readableBytes=963134
    at org.apache.activemq.artemis.api.core.SimpleString.readSimpleString(SimpleString.java:183)

In addition to this, the warning:

    AMQ212054: Destination address=... is blocked. If the system is configured to block make sure you consume messages on this configuration.

To fix this, I went into the docker and checked out our /amq/broker/data/large-messages folder, and moved all those files somewhere else. It threw a bunch of exceptions, but new messages seem to be going through now.

But I am still getting the AMQ212054 'destination blocked' warning.

So, how do I

a) get rid of the warning

b) fix this going forward?

I have looked at the docs, but I don't see anything in particular that would help. There's a minLargeMessageSize field, but would setting it make any difference? Then would I be checking the size of the XML before sending, and then have some if/else statement, to either send with producer.send(message); or as a ByteMessage, like section 9.4/9.5, if it's a 'large' message?
