Symfony2 在生产环境中出现故障

ubuntuamazon-ec2symfonydebianproduction

我们本周在生产环境中部署了我们的第一个Symfony2网站。
但是，在服务器上出现了一些奇怪的问题，但我们无法在本地复现该问题。我们在其他服务器上进行了测试，并捕获了相同的错误。如果有帮助的话，我们尝试了亚马逊EC2上的Ubuntu AMI和其他服务器上的Debian。同时使用了apache2+mod_php和nginx+php-fpm，php版本为5.3.3。Symfony为2.0.9。
某些请求只返回空白屏幕，并在错误日志中出现以下错误：

我们目前遇到了问题，但无法确定具体原因。有其他人也遇到过这样的问题吗？如果有任何帮助，我们将不胜感激。
你尝试过重新构建你的 bootstrap.php.cache 文件吗？ - Florian Klein

你还需要在CLI环境和Web环境下清除你的APC缓存。 - Florian Klein
重建bootstrap.php.cache没有结果。 - user432904
我不知道。第1152行的bootstrap.php.cache文件内容可能很有趣。 - Florian Klein
intl已安装，是的。我们使用ApcUniversalClassLoader，在autoload.php中实例化。在bootstrap.php.cache中有UniversalClassLoader的代码。 - user432904

根据我的经验，当你遇到像这样的奇怪错误时，特别是在不合理的地方看到随机的“非对象”问题时，问题总是出在内存上。确切地说，一个对象被创建，但是然后这个对象在内存中丢失了，所以到了下一行，它就不再是一个对象了。我只见过几次这种情况，但它总是与APC的问题有关。事实上，在我上一份工作中，我们在升级到PHP 5.3后遇到了类似的问题 - 它大部分时间都能正常工作，但最终APC会耗尽内存，我们就会遇到这些错误。当时（大约一年前），从谷歌搜索来看，PHP和APC在某些情况下存在一些问题。我肯定会调查APC - 我真的认为这是你的问题。具体而言，APC没有清除旧内存以腾出空间来存储新内容。

祝你好运！

即使完全关闭了apc，也没有任何效果。相同的错误，但这次没有ApcUniversalClassLoader行。 - user432904

好的，我认为我们找到了解决这个问题的办法。当我们将服务器上的php升级到最新版本5.3.10时，奇怪的错误都消失了。只是这么简单。可能是一些php 5.3.3的bug，我不知道。我们在版本日志中也没有找到相关内容。

这个周末，我们将测试另一台安装有freebsd和5.3.8的机器。

感谢每个试图帮助我们的人。

你尝试过升级到Symfony 2.0.10吗？
