一个dwr服务器推送消息错误

[oh_Boo]

一个web聊天页面,在公司电脑XP 本地测试没问题. 发送消息频率很快也没错,但是回到家系统是WIN7.发送快了就会弹出提示failed to read input. 这个也和网速有关?
贴下我的服务器类:

public class ChatService {
	public static List<User> users = new ArrayList<User>();

	public String registerUser(String name, HttpServletRequest request) {
		User user = new User();
		user.setName(name);
		user.setId(request.getSession().getId());
		WebContextFactory.get().getScriptSession().setAttribute("user", user);
		users.add(user);
		
		updateUsers();

		return user.getId();
	}

	public void updateUsers() {
		Browser.withAllSessions(new Runnable() {
			public void run() {
				Util.removeAllOptions("users");
				Util.addOptions("users", users, "name");
				Util.removeAllOptions("receiver");
				Util.addOptions("receiver", users, "name");
			}
		});
	}
	
	public void send(final String sender, final String receiverid, final String msg) {
		
		Browser.withCurrentPageFiltered(
			new ScriptSessionFilter() {
				public boolean match(ScriptSession session) {
						if (session.getAttribute("user") == null)
							return false;
						else
							return ((User)session.getAttribute("user")).getName().equals(receiverid);
					}
				}, 
			new Runnable() {
				public void run() {
					Collection<ScriptSession> colls = Browser.getTargetSessions();
					for (ScriptSession scriptSession : colls) {
						ScriptBuffer script = new ScriptBuffer();
						SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
						String date = format.format(new Date());
						System.out.println(msg);
						String message = "<p><p style='color:blue'>"+sender+"  "+date +"</p>" + msg+"</p>";
												script.appendScript("test(");
						script.appendData(message);
						script.appendScript(",");
						script.appendData(receiverid);
						script.appendScript(");");
						scriptSession.addScript(script);
					}
				}
			}
		);
	}
		
	public void list(){
		Browser.withAllSessions(new Runnable() {
			public void run() {
				Collection<ScriptSession> colls = Browser.getTargetSessions();
				for (ScriptSession scriptSession : colls) {
					System.out.println(scriptSession.getId());
				}
			}
		});
	}
}

大家看看能帮忙解决下不,或者原因看看.
