Subject [jira] [Updated] (AMQ-3942) Certain messages do not expire in the embedded broker
Date Thu, 26 Jul 2012 07:06:35 GMT

     [ https://issues.apache.org/jira/browse/AMQ-3942?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pedro de Lara updated AMQ-3942:
-------------------------------

    Description: 
When sending messages to a queue and waiting for the expiration task to expire them, only
some of the expired messages are moved to the DLQ. Other expired messages (With same expiration
time as the ones moved to the DLQ) just sit in the queue, stuck until all messages in the
queue expire, at which point they are all moved to the DLQ.

This seems to happen only in the embedded broker (configured in activemq.xml) and only for
some messages (It seems the size of the message however I am uncertain if the content could
actually cause such an issue).

A Unit Test is provided that shows the issue. The unit test includes a boolean that can be
changed to run it towards a created broker (instead of the embedded one) for comparison purposes.

An activemq configuration file (activemq.xml) is also provided as it is the only file that
has been changed from default installation.

Test were done on activeMQ running on both JDK 1.7.0_03 and 1.6.0_33 with the activemq executable
script being pointed towards those versions (Instead of "auto").
