In previous versions of JBoss EAP, the JMS configuration property address-full-policy was set to BLOCK in the product's configuration, meaning that once the maximum configured capacity for messages to a given address was reached, producers would be prevented from sending any further messages to that address.
This behaviour has been modified to conform more closely with customer expectations. The new default setting is PAGE, which pages messages recieved while the consumer is over the maximum capacity to disk. These messages will occupy disk space if they are not consumed.
This behaviour can be modified by setting the address-policy-full configuration back to BLOCK (or, additionally DROP or FAIL) if required.
