我正在使用简单的 qpid java 客户端，它使用来自代理的消息并通过 SOAP 服务将其发送到。在生产者端，我们将所有数据放到映射中，然后将此映射发送到 qpid。这是一个片段：
QueueSender conBusQueueSender = (QueueSender) Component.getInstance("conBusQueueSender");
QueueSession queueSession = org.jboss.seam.jms.QueueSession.instance();
Map<String,Object> map = new HashMap<String,Object>();
map.put("applicationId", applicationId);
map.put("soapAction", "urn:changeApplicationStatus");
map.put("soapXML", changeApplicationStatusString);
MapMessage message = queueSession.createMapMessage();
message.setObject("map",map);
conBusQueueSender.send(message);
在客户端，我们接收消息并尝试通过 SOAP 将其发送到 Web 服务
while (true) {
MapMessage m = (MapMessage) consumer.receive();
@SuppressWarnings("unchecked")
Map<String, Object> map = (Map<String, Object>) m.getObject("map");
SOAPMessage message = createSoapMessage(map);
while (true) {
try {
SOAPMessage result = makeSoapCall(message, (String)map.get("applicationId"), (String)map.get("soapAction"));
if(result.getSOAPBody().hasFault()){
System.out.println("SOAPFault: "+result.getSOAPBody().getFault().getFaultString());
System.out.println("SOAPMessage tried to send: " + (String)map.get("soapXML"));
}
m.acknowledge();
// if we came here successfully -> break and process next message
break;
} catch (SOAPException e) {
// if we have exception -> sleep and retry
e.printStackTrace();
Thread.sleep(1000L);
continue;
}
}
}
一切正常，但是当消费者尝试发送更大的消息〜66KB时，它只会打印此错误：

并且没有任何错误，例如“队列“总线状态队列”上超出队列容量阈值”。怎么了？
