Hi,
I'm using ActiveMQ 5.9.1
Recently I started to get a lot of messages into the DLQ. Nevertheless,
from the logs, these messages are being sent into the DLQ by the producer,
not the consumer.
The messages in the DLQ have an additional attribute:
dlqDeliveryFailureCause
with the value:
java.lang.Throwable: duplicate from store for queue:
production@engineMessage
The activemq.log shows a lot of warnings similar to the following segment:
2015-02-09 02:16:47,137 | WARN |
org.apache.activemq.broker.region.cursors.QueueStorePrefetch@4d0a81a5
:production@engineMessage,batchResetNeeded=false,storeHasMessages=true,size=1,cacheEnabled=true,maxBatchSize:2,hasSpace:true
- cursor got duplicate:

redirecting for dlq processing | org.apache.activemq.broker.region.Queue |
ActiveMQ BrokerService[activemq-aws-prod] Task-39710
Any idea what could be the cause? We had changes in our system but these
don't seem to affect how we add messages into the queue.
Any pointers are appreciated.
