[jira] Commented: (QPID-1658) JMS client OutOfMemoryError when
sending 4k messages in rapid succession
[ https://issues.apache.org/jira/browse/QPID-1658?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12672395#action_12672395 ]
Rajith Attapattu commented on QPID-1658:
----------------------------------------
Douglas,
Are you using the c++ broker or the java broker?
Depending on which broker the JMS clients takes a different code path.
For the java broker the 0-8/0-9 code path is activated and uses MINA as the transport.
For the c++ broker the 0-10 code path is activated and uses a plain java.io based transport.
If it's the java broker you could then try to set -Dprotectio=true when starting the JMS client to ensure that the underlying MINA buffers don't grow unbounded.

> Key: QPID-1658
> URL: https://issues.apache.org/jira/browse/QPID-1658
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: M4
> Environment: Ubuntu 8.04 Hardy
> Reporter: Douglas Pew
> Attachments: Consumer.java, Producer.java
>
>
> The JMS bindings will throw an OutOfMemoryError when sending 4k or larger messages in rapid succession. The message producer's heap will continue to fill up until exhausted.
> To repeat this error edit the class org.apache.qpid.example.jmsexample.direct.Producer to produce 100000 messages and 4k message sizes. I will submit source code.
