I'm using the 5.1.0 beta release of AS5 Previously I had been using the following in my bridge configuration: | <attribute name="MaxBatchSize">1</attribute> | <attribute name="MaxBatchTime">-1</attribute> | This worked but was very inefficient so I changed to this: | <attribute name="MaxBatchSize">20</attribute> | <attribute name="MaxBatchTime">200</attribute> | If I send 23 messages, only 20 get transported across the bridge. I must send another 17 before the left over 3 get sent. There is jira issue related to this: https://jira.jboss.org/jira/browse/JBMESSAGING-1186 A fix never seemed to be implemented for this. Note that unlike the above issue the remaining messages are never sent until the maxBatchSize is reached again. We will stick with a batch size of 1 as this is a suitable workaround in the short term on our production server. Any ideas greatly appreciated.
