Server is already running in Rails

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).
Solution

  • 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.
