我使用故障轉移協議，SSL（NIO）和simpleAuthenticationPlugin，在ActiveMQ中有大量（1000）個客戶端出現問題。經過一段時間brocker剛剛停止。我正在尋找日誌文件中的一些錯誤，但我沒有發現任何東西 - 它是空的。ActiveMQ中的大量SSL客戶端
服務器 - Ubuntu的15.04，Java版本 「1.7.0_80」 基本架構信息
我有一個分佈式系統。它由C＃客戶端（節點）和一個Java客戶端（管理器）組成。我正在使用ActiveMQ 5.12.1安裝在管理器工作的同一臺主機上。通信僅在C＃客戶端和經理之間進行。 C＃客戶端彼此之間不進行通信。
每個客戶端（C＃和java）都使用一個隊列進行偵聽。當管理員想要發送消息給節點時，它使用一個唯一的隊列來完成它。當一個節點想要與經理溝通時，它會向經理隊列發送消息。 管理器每分鐘輪詢每個節點。經理有2個線程，一個接收消息。其次，瞭解有關信息
這裏節點是代碼：
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("failover://(nio+ssl://localhost:61617)");
connectionFactory.setUserName("user");
connectionFactory.setPassword("password");
Connection connection = connectionFactory.createConnection();
connection.start();
connection.setExceptionListener(this);
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("manager");
MessageConsumer consumer = session.createConsumer(destination);
Message message= null;
while (!stop) {
try{
message = consumer.receive();
if (message instanceof TextMessage) {
TextMessage textMessage = (TextMessage) message;
String text = textMessage.getText();
processMessage(text);
}
}
catch (Exception e){
Logger.getInstance().log("Exception in message receive loop continue");
}
}
經理代碼發送消息：
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("failover://(nio+ssl://localhost:61617)");
connectionFactory.setUserName("user");
connectionFactory.setPassword("password");
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
while(!stop) {
for (everynode) {
Destination destination = session.createQueue(uniqueNodeQueue);
MessageProducer producer = session.createProducer(destination);
producer.setDeliveryMode(DeliveryMode.PERSISTENT);
TextMessage message = session.createTextMessage("in");
producer.send(message);
producer.close();
}
Thread.sleep(time);
}
// Clean up
session.close();
connection.close();
C＃客戶端使用Apache.NMS.ActiveMQ;

}

{

//txtMessage.NMSPersistent = false;

當我用NIO一些有趣的切日誌：

NIO之前，我已經試過只SSL中，結果是相同→brocker關機。
任何任何想法？
