Cursors not dealing with topic memoryLimit overflow
---------------------------------------------------
Key: AMQ-3738
URL: https://issues.apache.org/jira/browse/AMQ-3738
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.5.1
Environment: OSX, Apple Java Runtime 1.6.0_26
Reporter: Jakub Korab
I have defined a topic with a memoryLimit of 1mb using a
fileDurableSubscriberCursor. I would expect that sending messages to a durable
subscriber through that topic would result in more than 1mb worth of messages
being able to be sent. Instead producer flow control kicks in at the 1mb limit.
To test this I am using the Maven activemq-perf plugin with a single consumer
and producer:
$ mvn activemq-perf:producer -Durl=tcp://localhost:61616
-Dproducer.destName=topic://orders
$ mvn activemq-perf:consumer -Durl=tcp://localhost:61616
-Dconsumer.durable=true -Dconsumer.destName=topic://orders
-Dconsumer.recvDelay=100
This does not match the behaviour described in
http://activemq.apache.org/my-producer-blocks.html or
http://activemq.apache.org/message-cursors.html
Going by the docs, I would expect messages to get paged out to disk until the
systemUsage/tempUsage limit fills up.
This same behaviour happens using the default cursor configuration.
Attached are the activemq-perf pom and activemq.xml.
