I have sometimes seen this error, but I'm not sure what causes it.  I only see it occasionally
while testing other features and I haven't been able to reproduce it reliably.  If you are
able to, could you explain how in more detail?

There's another issue in 5.4.2 which can cause an ajax client to not receive all messages
intended for it.
https://issues.apache.org/jira/browse/AMQ-3094

I recently checked in a fix for this issue, so could you try your tests with a nightly snapshot
build and see if that helps at all?
