Subject [jira] [Commented] (AMQ-6708) When reading from a topic, messages will intermittently have empty body text
Date Tue, 20 Jun 2017 19:36:00 GMT

    [ https://issues.apache.org/jira/browse/AMQ-6708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16056333#comment-16056333

Christopher L. Shannon commented on AMQ-6708:
---------------------------------------------

What kind of messages are you sending?  Does the issue still happen if you change message
type? (String, bytes message, etc, or persistent or non-persistent)

The main thing is just trying to narrow down what the issue could be as right now it will
be hard to figure out as your setup is complex.  For example, does the issue happen if you
only have 1 consumer instead of multiple?  Does the issue happen if you just use a standalone
broker and no network of brokers?  Does the issue happen if Camel is not used?  The simplest
setup possible to reproduce the issue the better.  For example, If you are able to reproduce
it with a standalone broker without Camel it would be a lot easier to debug.

> 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.
