ActiveMQ提示“waiting for space to send transacted message”怎么解决？

[u011878308]

ActiveMQ 5.8 , .NET 4.0 , 用C#写了一个测试程序：
启动10个线程，每个线程中有一个producer发送一万条消息。
创建producer的是相同的session,session设置了AcknowledgementMode.Transactional;
producer发完消息后调用一次session.commit();
结果得到标题中提示的错误。
请问这个问题怎么排查？我使用的是AMQ的默认设置

使用session让我感觉不是那么,除非不得而以,

activemq要发送和接收必须创建一个session诶。2楼的意思是说我不该用事务吧？我是因为测试的时候发现 producer 采用事务的方式发送可以显著提高性能。

从字面意思理解的话貌似是缓冲队列满了。。。。。

感觉像是模式设置的不对：enum AcknowledgeMode { /** * With this acknowledgment mode, the session automatically * acknowledges a client's receipt of a message either when * the session has successfully returned from a call to receive * or when the message listener the session has called to * process the message successfully returns. */ AUTO_ACKNOWLEDGE, /** * With this acknowledgment mode, the session automatically * acknowledges a client's receipt of a message either when * the session has successfully returned from a call to receive * or when the message listener the session has called to * process the message successfully returns. Acknowledgments * may be delayed in this mode to increase performance at * the cost of the message being redelivered this client fails. */ DUPS_OK_ACKNOWLEDGE, /** * With this acknowledgment mode, the client acknowledges a * consumed message by calling the message's acknowledge method. */ CLIENT_ACKNOWLEDGE, /** * Messages will be consumed when the transaction commits. */ SESSION_TRANSACTED, /** * Message will be acknowledged individually. Normally the acks sent * acknowledge the given message and all messages received before it, this * mode only acknowledges one message. */ INDIVIDUAL_ACKNOWLEDGE }; 试一下吧
