解决方案
应该跟上周四报出来的struts漏洞有关，升级到最新的struts版本试试
解决方案二：
http://www.oschina.net/question/1436888_152963兄弟伙 速度啊，看解决方案
解决方案三：
我去都遇到了啊我上周五开始，到现在 纠结惨了，求解决拌办法额。
解决方案四：
我也遇到这个问题了，而且是在一个稳定了几个月的系统上，周五晚上突然间出现的，然后一直到现在，不停的出问题，重启了过不了多一会就又挂了
解决方案五：
有哪位解决了吗？
解决方案六：
项目一直都是正常运行的，就今天出现这种问题！一直在试着解决，更换版本也搞不定！如果重启tomcat就可以正常运行一会，但是十几分钟之后就会继续出现这种错误
解决方案七：
大家都是外网可访问的吗，我们同样的系统在内网没有报这个错的
解决方案八：
是SSH吗？struts版本是什么？我觉得struts 漏洞的可能性比较大。
解决方案九：
服务器linux，tomcat+apache；网站之前一直正常，今天出现的这种问题，把apache和tomcat重启之后可以正常，但是一段时间之后就报错不行了，有谁解决的没?
解决方案十：
我们是可以外网直接访问，之前没事，从上周五下午开始的，每隔一段时间出现一次
解决方案十一：
我这边是昨天出现这样的情况，你们都是什么样的情况。什么服务器，环境是啥样的？
解决方案十二：
我也出现同样的问题，你们解决了吗
解决方案十三：
我们也出现了，会不会是在攻击8080端口
