项目工程报错：
17-08-07 10:00:39 ERROR DefaultMessageListenerContainer:947 - Could not refresh JMS Connection for destination ‘queue://settlementToErpListener‘ - retrying using FixedBackOff{interval=5000, currentAttempts=46725, maxAttempts=unlimited}. Cause: Connection closed
暂时解决方案，重启监听项目工程
分析这个问题时发现：
mq不能连接问题，不能创建连接，内存溢出，mq内存设置1g，连接最大1000，发现机票业务系统到mq端口占用81条，正常情况是往mq发送数据，占用连接，发送完成，连接关闭。目前是一致占用。
尝试解决方案：
1、重装jdk，之前版本jdk未关闭，一直在更新，之前虽然关闭更新，还是重新安装
2、重启机票系统，监控机票系统到mq端口占用情况，占用连接情况。
3、重启mq，监控mq内存占用情况，mq服务器，目前16g，已用24%
目前出现问题时间频率大概 10天一次。。
待观察。。2017/8/17
