Question

我用谷歌搜索并阅读了很多网站，包括stackoverflow上的大部分相关文章，我无法弄清楚如何解决这个错误：

“从守护进程收到的截断或超大响应标头”

此服务器失败：

Apache 2.2.15
mod_wsgi 4.4.13

此服务器运行相同的代码而没有截断的问题：

Apache 2.4.6
mod_wsgi 3.4

不幸的是，我没有选择升级Apache或降级mod_wsgi以使其工作。我已经尝试更改header-buffer-size，但它似乎没有做任何事情（仍然失败）：

http://modwsgi.readthedocs.io/en/develop/configuration-directives/WSGIDaemonProcess.html?highlight=truncated

header-buffer-size = nnn定义响应的最大大小 header / value可以是从WSGI应用程序返回的。该默认大小为32768字节。这可能需要覆盖在哪里返回过大的响应标头，例如在自定义中使用WWW-Authenticate的身份验证挑战方案报头中。

有关如何解决这个问题的想法吗？

在我的情况下，我使用aws EC2和eb服务器，并显示相同的错误消息。经过详细检查，我发现这只是简单的内存错误。当我扩展我的实例时，问题就解决了。

从official page开始，在Elastic Beanstalk控制台中配置EC2实例：

打开Elastic Beanstalk控制台。
导航到您所在环境的管理页面。
选择配置。
在Instances配置卡上，选择Modify

我尝试过上面列出的方法来解决问题，在03_scipy.config文件中添加以下代码并将其保存到.ebextension目录。但是，它没有用。

container_commands:  
  AddGlobalWSGIGroupAccess: 
    command: "if ! grep -q 'WSGIApplicationGroup %{GLOBAL}' ../wsgi.conf ; then echo 'WSGIApplicationGroup %{GLOBAL}' >> ../wsgi.conf; fi;"
