https://issues.apache.org/jira/browse/ARTEMIS-1993
The following issue is occasionally seen when multiple short lived concurrent connections consume from the same queue. When the issue occurs, there tends to be a swathe of these messages written to the logs at one time. Apart from the error message, there is no other obvious functional defect.
The issue has been reproduced with Artemis 2.5.0 and master (f0c13622ac7e821a81a354b0242ef5235b6e82df).
