When I am starting rails server using rails s command it is showing A server is already running. Check C:/Sites/folder/Pids/Server.pids

When I open the file it is outputting a 4 digit number only so how could I resolve this issue ?

FYI

  1. No other instance of Rails cmd is running this time.
  2. Checked Task manager but only cmd.exe is showing no else process is running. (using Windows).

Remove the file: C:/Sites/folder/Pids/Server.pids

Explanation In UNIX land at least we usually track the process id (pid) in a file like server.pid. I think this is doing the same thing here. That file was probably left over from a crash.
