Are we talking about 204 No Content, or 404 Not Found? Your first sentence seems to have put one error code and a different error message together, though your last sentence makes it seem like you're talking about a 204.
What URL are you hitting when you get this response? And I assume you're doing this in the context of a websocket consumer? http://activemq.2283324.n4.nabble.com/activeMQ-topics-via-rest-missing-messages-td4677698.html seems to indicate that you'll get a 204 when attempting to GET or DELETE from a topic subscription with no unconsumed messages. Could that be what's going on for you? http://activemq.2283324.n4.nabble.com/204-No-Content-after-sending-message-to-queue-with-active-consumer-td4255617.html also references getting a 204, but it sounds like a more consistent failure, whereas your error sounds like often it works and occasionally it doesn't.
