我在使用Symfony2时遇到了这个奇怪的错误。在localhost中一切正常，但是当我在服务器中尝试它时，我得到了这个PHP错误：
[06-Mar-2013 22:04:50 UTC] PHP Fatal error: Uncaught exception 'Symfony\Component\DependencyInjection\Exception\InvalidArgumentException' with message '[ERROR 3070] complex type 'service': The content model is not determinist.

它似乎与XMLFile Loader有关，但我的文件中没有做任何更改
答案 0 :(得分：15)
这是libxml2中的错误 - 您使用的是RHEL还是CentOS？查看https://rhn.redhat.com/errata/RHBA-2013-0591.html，如果您不能等待通过yum update发布更新，那么您可以降级到早期版本：
yum downgrade libxml2-2.6.26-2.1.21.el5_9.1
