我有一个运行在Debian 8（杰西）上的Apache Web（2.4.10版）服务器。它主要用作SVN仓库服务器。几周以来它一直运行良好，但突然，当我试图从Web浏览器列出SVN仓库时，出现了一个内部错误，如下所示：
Apache Internal Error & Authentication
正如您所看到的，身份验证仍然工作正常。
我运行了以下2个命令：系统状态apache 2.服务和日志ctl-xn
commands
但这对我帮助不大，也许我遗漏了什么？我最近没有修改任何与Apache相关的配置文件（甚至没有修改任何与Apache相关的配置文件）：既不是主apache conf文件，也不是任何vHost conf文件。我尝试重新启动Apache，它确实重新启动了，但Web服务器仍然遇到内部错误。

这会不会来自mod_wsgi正在运行的Python版本，而这与mod_wsgi显然期望的不同？
