ActiveMQMapMessage stay in memory causing leaks
-----------------------------------------------
Key: AMQ-2918
URL: https://issues.apache.org/activemq/browse/AMQ-2918
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.4.0
Environment: Windows XP
Reporter: ashwini kuntamukkala
I am running embedded broker in a spring container. During a volume test, I
forward messages to a dead letter queue. ActiveMQMapMessage that are being
redirected to dead letter queue stay in memory. So, if I forward 15000 messages
to dead letter queue, all 15000 messages will be in memory. These are
persistent messages.
I want to have a smaller memory footprint. Why are the activemqmapmessages
staying in memory. the ones that were successfully processed get deleted just
fine.
This is jmap -histo output
14: 19826 3647984
org.apache.activemq.command.ActiveMQMapMessage
28: 19791 791640 org.apache.activemq.command.ActiveMQQueue
total of 19K+ activeMqMapMessages and ActiveMQQueue instances...
Since these are dead letter messages, why does ActiveMQ need to hold references
to these messages in memory??

I tried using the filequeuecursor: after a while the broker stopped responding
because of the following error.
