      While a receiving transaction is committed to a paging operation, if the page is complete, a transaction operation deletes it. Previously, the transaction operation might delete the page before the receiving transaction could access it. This caused the receiving transaction to fail to find a message. In that case, you saw an exception. This issue is now resolved.

      1. Download and extract the attached broker.zip file. broker1 is the master and broker2 is the slave.
      2. Create the master/slave setup using attached broker files.
      3. Run master and slave broker.
      4. Run the attached test script (testScript.sh) which produces and consumes messages with high volume.
      5. After a few iterations the following logs appear when the consumer is running:

      [org.apache.activemq.artemis.utils.actors.OrderedExecutor] Invalid messageNumber passed = PagePositionImpl [pageNr=2, messageNr=11127, recordID=6573510] on null: org.apache.activemq.artemis.core.paging.cursor.NonExistentPage: Invalid messageNumber passed = PagePositionImpl [pageNr=2, messageNr=11127, recordID=6573510] on null

      6. Incorrect message count is displayed for this particular queue on hawtio console

      Expected
      1. This exception should not appear under high load
      2. Correct message count should be displayed on hawtio console.
