Message Lost at Broker

[Robert Dare <ro...@gmail.com>]

Good morning,

I am trying to isolate an issue where messages appear to get lost to
ActiveMQ.  When the system gets into this state, some messages never arrive
at ActiveMQ.  I am monitoring the application server (tomcat 7) log file,
activemq log file and the ActiveMQ admin console (enqueued & dequeued
counts).

I see this message in the tomcat7 log, which indicates the message was
produced and sent:

The log seems to indicate that the message was produced and that the
transaction committed successfully.

How can I further debug this issue?

Thank you in advance.

Hi Robert,

Have you checked your Dead Letter Queue (DLQ) in ActiveMQ? Your lost messages may have ended up there!

Regards,

Arnoud
