xfile开发webService报错，灵异事件，求解救！
java，用xfile开发webservice服务端接口，让别人调用，偶尔会报一下错误（不是很常见，不能重现报错），不知道是哪里出了问题？下面是报错信息！

------解决思路----------------------
重点需要排查下at cn.com.gxlu.webservice.impl.QueryWebServiceImpl.findInfoByAddr(QueryWebServiceImpl.java:99)
at cn.com.gxlu.webservice.impl.QueryWebServiceImpl.query(QueryWebServiceImpl.java:30)这两处，都做了什么操作，是不是会有不正确的IO操作。
