tomcat出错: Unexpected end of file from server
tomcat开的时间开了.   tomcat没有报什么错误.   客户端就是不能访问.

我写了程序去访问
-------------------------------
try
{
HttpURLConnection   c   =   (HttpURLConnection)   new   URL( "http://www.ypworld.cn/ ").openConnection();
InputStream   is   =   c.getInputStream();
is.read();
is.close();
}   catch   (Exception   ex)
{
ex.printStackTrace();
}

显示出的报错
-----------------------

我用的是tomcat   v6.0.13     jre是6u1


哪位知道是什么原因??     是不是并发太大了??         现在一天要重启好几次tomcat。
