ActiveMQ拋出不匹配的確認異常

Question

WARN | Async error occurred: javax.jms.JMSException: Unmatched acknowledge: MessageAck {commandId = 30, responseRequired = false, ackType = 2, consumerId = ID:PC02-DT-009-52405-1421153309991-1:3:10:1, firstMessageId = ID:PC02-DT-009-52360-1421152976467-1:4:11:1:1, lastMessageId = ID:PC02-DT-009-52360-1421152976467-1:4:11:1:1, destination = queue://DATA.DESTINATION, transactionId = null, messageCount = 1, poisonCause = null}; Could not find Message-ID ID:PC02-DT-009-52360-1421152976467-1:4:11:1:1 in dispatched-list (start of ack)

這是我在activeMQ日志中獲得的異常。 場景：我有10個消費者，我在消費者正在收聽的目標隊列中有100條消息。 消費者正在獲取大約10-20條消息的消息，但最終會因上述異常而停止從隊列中獲取消息。 我的理解是，只有在返回確認時才會給消費者一個新的消息（如果我是對的）JMS容器：

<jms:listener-container container-type="default" connection-factory="jmsConsumerConnectionFactory" acknowledge="auto"> <jms:listener destination="DATA.DESTINATION" ref="jmsMessageListener" concurrency="10-15" method="onMessage"/> </jms:listener-container>

非常感謝任何幫助，謝謝！

好吧，讓我感謝自己回答這個問題。 顯然，當通過httpclient連接到數據庫時，消費者遇到了一些異常，這會殺死所有的消費者線程。 無論如何，沒有任何異常發生的任何人都可以通過以下方式嘗試解決：1。在activeMQ配置“conf / activemq.xml”中增加內存限制2.嘗試在消息本身消息中將確認方法更改為“已處理”或確認。確認（）;
