Justin Bertram updated ARTEMIS-4192:
------------------------------------
Description:
Steps to reproduce:
# Create a broker from default settings
# Add the following to {{broker.xml}} to enable paging for the TEST queue.
{code:xml}
<address-setting match="TEST">
<max-size-messages>25000</max-size-messages>
</address-setting>{code}
# Use {{artemis producer}} to dump 2 million messages into the TEST queue
{noformat}
./bin/artemis producer --message-count 20000 --threads 100{noformat}
# Call {{removeAllMessages}} using the console or via Jolokia:
{noformat}
curl -sH "Origin: http://localhost:8161"; -u admin:admin
'[http://localhost:8161/console/jolokia/exec/org.apache.activemq.artemis:broker=!%220.0.0.0!%22,component=addresses,address=!%22TEST!%22,subcomponent=queues,routing-type=!%22anycast!%22,queue=!%22TEST!%22/removeAllMessages()']{noformat}
The broker will start producing Java Heap space errors and shutdown.
I managed to take a heap dump and I noticed there are quite a few Artemis
classes with an instance count of around one million, and then several more
around 20,000. I included the latter because messages seem to be bundled into
transactions of 500.
