Subject Re: Duplicate messages sent in Active MQ 5.7
Date Wed, 04 Dec 2013 19:56:57 GMT
Yes. I feel this is an error & not expected behavior. The first message was
processed successfully by my consumer at 12:04:11.002 PM. There were no
network or database issues or failover which took place between 12:04 to
12:21. At 12:22, I restart Active MQ and immediately lots of such messages
get replayed automatically. The producer did not send the dupe messages. I
confirmed looking at the log file. 
Always we connect to the 1st broker. I am using Spring configuration as
shown below. All consumers connect to broker 1. Reading the different
configuration, I am not sure if I have to use enableAudit="true" in
activemq.xml or add jms.optimizeAcknowledge=true in my brokerURL below.

Can I check the ACTIVEMQ_MSGS table before I restart to check what are the
messages in the container queue://Input and do I need to truncate this table
before every restart?

Can you provide me some guidance on the settings?

Thanks
