Subject [jira] Commented: (QPID-1658) JMS client OutOfMemoryError when sending 4k messages in rapid succession
Date Tue, 10 Feb 2009 20:53:59 GMT

    [ 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:


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.

>         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.
