[jira] [Updated] (QPID-8144) [Broker-J] Memory compaction does not
run when used direct memory exceeds 2GB
[ https://issues.apache.org/jira/browse/QPID-8144?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Keith Wall updated QPID-8144:
-----------------------------
Summary: [Broker-J] Memory compaction does not run when used direct memory exceeds 2GB (was: [Broker-J] Memory compaction not running when allocated direct memory exceeds 2GB)
> [Broker-J] Memory compaction does not run when used direct memory exceeds 2GB

> Key: QPID-8144
> URL: https://issues.apache.org/jira/browse/QPID-8144
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: qpid-java-broker-7.0.2, qpid-java-6.0.7, qpid-java-6.1.3, qpid-java-6.0.8, qpid-java-broker-7.0.0, qpid-java-6.1.5, qpid-java-broker-7.0.1
> Reporter: Keith Wall
> Priority: Blocker
> Fix For: qpid-java-6.1.6, qpid-java-broker-7.0.3
>
>
> The Broker-J uses direct memory for the caching of message content and IO buffers used for AMQP messaging. If direct memory utilisation exceeds 2GB, owing to a defect the memory compaction mechanism does not get triggered. This problem may lead to an {{OutOfMemoryError: direct}} condition. Whether this condition manifests will depend on the message consumption patten - if the consumption pattern leads to sparsely occupied buffers the problem will occur.
