jmeter做mq消息压测，线程小的时候正常， 线程调大后就报错（线程超过CPU），错误信息如下：
com.ibm.msg.client.jms.DetailedJMSException: JMSWMQ0018: Failed to connect to queue manager 'MQCHNTPBS01' with connection mode 'Client' and host name 'xxx.xxx.xxx.xxx(xxxxx)'. Check the queue manager is started and if running in client mode, check there is a listener running. Please see the linked exception for more information
