             Summary: Journal export runs out of memory 
                 Key: ARTEMIS-4019
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-4019
             Project: ActiveMQ Artemis
          Issue Type: Bug
         Environment: SUSE Linux Enterprise Server 15 SP3

This might be two separate bugs:
 # After upgrading from version 2.22.0 to 2.25.0 we were facing a situation where messages, already queued or paged before the upgrade are not delivered to consumers. New messages, arriving at the broker after the upgrade were handled normally.
 # To avoid the above situation on other nodes, we wanted to export the old journal and reimport it before restarting the upgraded version. The export however runs OOM:
