Was this related to the client or server side? While testing ActiveMQ 5.4.1 I discovered message loss when the master broker fails over to slave.
This was using NMS though and I think I narrowed it down to an issue with the latest version of NMS. The issue seems very similar so am wondering now if it was actually ActiveMQ v5.4.1 causing the issue. -Thanks! -- View this message in context: http://activemq.2283324.n4.nabble.com/VOTE-Apache-ActiveMQ-5-4-2-tp3058930p3060525.html Sent from the ActiveMQ - Dev mailing list archive at Nabble.com.
