在消费者端使用PooledConnectionFactory建立与MQ服务器的连接，启动的时候初始化10个消费者。相关代码如下：

protected JMSConnectionUtill(String MQ_LOCATION,String userName,String password) { this.MQ_LOCATION=MQ_LOCATION; this.userName=userName; this.password=password; // ConnectionFactory ：连接工厂，JMS 用它创建连接 ActiveMQConnectionFactory connectionFactory = null; if(StrKit.notBlank(userName) && StrKit.notBlank(password)){ connectionFactory= new ActiveMQConnectionFactory(userName, password, MQ_LOCATION); } else{ connectionFactory= new ActiveMQConnectionFactory(MQ_LOCATION); } pooledConnectionFactory = new PooledConnectionFactory(); pooledConnectionFactory.setConnectionFactory(connectionFactory); // 设置最大连接数 pooledConnectionFactory.setMaxConnections(100); // 设置最小 pooledConnectionFactory.setMaximumActiveSessionPerConnection(500); pooledConnectionFactory.setIdleTimeout(Integer.MAX_VALUE); }

但是连接总是隔一段时间就完全无征兆的自己关闭了。为此查了很久，都没有找到原因。哪位大神指导如何解决？
