Subject [jira] [Commented] (AMQ-6708) When reading from a topic, messages will intermittently have empty body text
Date Tue, 20 Jun 2017 15:53:00 GMT

    [ https://issues.apache.org/jira/browse/AMQ-6708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16055998#comment-16055998

Peter Boekelheide commented on AMQ-6708:
----------------------------------------

So our topology is pretty complicated, but I'll give you a couple of nodes to show the basic
idea. The four configuration files in question are included in the [^config.zip] attached
to this ticket.

We've got one broker, here mqbe03, with the configuration be03_activemq.xml and be03_camel.xml.
That broker is networked to another broker, 04, which I'm not showing here. They have rebalance
and their clients all do failover. 

Then there's a third broker, npqueue01, which has the configuration npqueue_activemq.xml and
npqueue_camel.xml. This broker is standalone, and uses its camel routing to pull from mqbe03
(or, if it's rebalanced of fails over, mqbe04).

Let me know if this isn't clear enough or you need more information.

> We've come across a problem with our brokers wherein messages consumed from a topic will
intermittently have null/empty body text. This is regardless of the type of consumer we use,
be it stomp or openwire. There doesn't seem to be any particular pattern to the null messages
that we can see, and they may be null for one consumer but the same message would have a body
for another consumer. While we can consistently reproduce it in the sense that we can connect
a consumer and wait for a period of time (usually a couple of minutes) and the issue will
occur, we can't seem to find the exact conditions under which the null message happens.
> I know this a relatively vague issue description, but I'm not sure what more you'd be
looking for right now. Please comment and let me know if you'd like more information. This
is currently a major problem for us, as it makes our topics unreliable.
