<div><br></div><div><br></div><div>Based on the log, the problem seems like related to "<b>NACKS Received</b>" and "<b>ChannelN</b>" code throw the TimeoutException with reply-code <b>406 </b>(PRECONDITION_FAILED).�</div>
<div><br></div><div>I check all RabbitMQ servers are still working fine and I believe the time I set for�<b>waitForConfirmsOrDie </b>(10000) should be sufficient enough.</div><div><br></div><div><br></div><div>Can you advise me on the problem? How to solve it?</div>
