Subject [jira] [Commented] (CAMEL-2740) Using static queue as a reply queue in InOut pattern causes memory leak
Date Wed, 09 Nov 2011 12:32:51 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-2740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13146985#comment-13146985

Claus Ibsen commented on CAMEL-2740:
------------------------------------

Okay I was using the default maven surefire memory settings which of course is low. 

So I increased the memory setting and have the test be able to run all 1000000 messages

{code}

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <argLine>-Xmx1024m -XX:MaxPermSize=512m</argLine>
        </configuration>
      </plugin>
    </plugins>
  </build>
{code}

> I am running JBoss, ActiveMQ and Camel for my application.   In the InOut pattern,  I
am using a predefined static queue as a reply queue.   After running for a while,  the memory
usage of JBoss keeps growing and growing until it hits outOfMemory error and app server is
totally hung.   I monitor the thread in jconsole,  I can see the jms connection/session keeps
growing and growing.   
> But once I switch to use temp queue for InOut pattern,  this problem goes away.
