原因：因为在tomcat重启的时候，因为之前的tomcat中的线程还没有完全关闭，新启动tomcat就会报这个异常

解决方案：

    网上有很多解决方案是将Context中的reloadable设置为false，但是我们项目没有设置context，既然是由于线程没有关闭导致的，那么将现有线程先关闭，然后在重启就可以了，使用python脚本如下（最好是写成一个脚本，两个还是比较麻烦的）

a.py

#coding:utf-8

import os

if __name__ == '__main__':

##重新加载前删除当前执行的app

   ret1 =  os.popen('curl --upload-file ./abc.war  -u admin:Pdmi1234 "http://172.17.1.57:8080/manager/text/deploy?path=/abc&update=true"')

   ##打印返回值

   print ret1.read()

   print '-------------------------------------------------'

   det1 = os.popen('curl -u admin:Pdmi1234 "http://172.17.1.57:8080/manager/text/stop?path=/abc"')

   print det1.read()

  等待a.py执行成功并且返回值都为OK，执行b.py

#coding:utf-8

import os

if __name__ == '__main__':

##重新加载前删除当前执行的app

   det11 = os.popen('curl -u admin:Pdmi1234 "http://172.17.1.57:8080/manager/text/start?path=/abc"')

   print det11.read()
