These /fastenv requests seem to come from some spammer-like activities. You may create this file in your public folder (to save your server from trying to match a controller and action each time), or just ignore these errors.

You should not be scared by these errors. They are nothing unusual in the big, bad Internet. Your application is just scanned by someone in search for some exploitable errors.

You don't have to do anything. Just write your code with security in mind.

About your 500 error. There MUST be something in the logfile, unless the request has not hit your Rails application. Do you have any other server in front of your app? Apache? Nginx? Check the logfiles created by these servers.
