我在openshift上运行python应用程序，redis作为数据存储。
过去几天该应用已停止工作
当我通过邮递员向我的应用程序发送请求时，我看到：
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /index.
Reason: Error reading from remote server
当我登录我的应用时：
$ rhc tail myapp
我明白了：

同样，这个应用程序一直运行良好，几周没有错误。认为我的“爱好”redis db已经满了，我尝试了flushall，但问题仍然存在。
我该如何解决这个问题？
