apache2的bug？404错误问题

[pwtitle]

apache2.0.55默认编译安装。
配置
ErrorDocument 404 http://192.168.1.111/404.php
在apache2遇到404错误时候可以正常跳转到404.php这个页面。
但是如果我改成
ErrorDocument 404 /404.php

页面死活都不跳转。
谁知道怎么搞的？

我刚换了一下。
ErrorDocument 404 /404.html 就可以但是
ErrorDocument 404 /404.php 就不行了。
在404.php的情况下apache 的error的内容如下：
[Wed Dec 14 17:53:53 2005] [error] [client 210.51.24.95] File does not exist: /usr/local/apache2/htdocs/xp

但是事实上我
直接访问 http://localhost/404.php是完全正确的。
