从上游读取响应头时，XDebug 无法打开远程调试文件“/var/log/xdebug.log”

Question

我正在使用 docker 进行开发，在我的磁盘上没有剩余空间之前，它完全没有任何问题（我的 Ubuntu 分区只有 30G）。所以我删除了所有不再运行/使用并且有足够空间的容器和图像。

再次启动我的应用程序后，我现在收到ContextErrorException以下消息

Warning: Header may not contain more than a single header, new line detected

当我查看error.log，这是内容

2017/04/29 12:53:13 [error] 13#13: *1 FastCGI sent in stderr: "PHP message: XDebug could not open the remote debug file '/var/log/xdebug.log'" while reading response header from upstream, client: 172.17.0.1, server: app, request: "GET /admin/dashboard HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost:8080"

我在两个环境（docker-container 和主机系统）中都做了以下步骤，
我进入/var/log/并看到没有文件，xdebug.log所以我创建了文件 - 仅用于测试目的 - 授予他们777权限并将所有者/组更改为相同作为我的项目文件/docker 文件

但是，错误仍然存​​在。我什至删除了所有容器和图像，不仅是未使用的容器和图像，而且完全从头开始构建。这看起来不像是 Docker 错误，因为它在磁盘空间已满之前都没有问题，对吧？

这是结果 php -i | grep xdebug
