I am on Windows, I got Instant Rails v1.3a (as mentioned in the book  
by Patrick Lenz- “Build your own Ruby on Rails web applications”).  
Now, going through the tutorial, I created new app shovell, then  
started WEBrick. When entered [http://localhost:3000/](http://localhost:3000/) for the first  
time, it was working.  
Then, after restarting, I again fired up WEBrick, but this time  
localhost is not working.  
After 10 minutes, Instant Rails is giving the message= Instant Rails:  
Server starting

What is this ??

Had a similar problem when i started. turned out i had some errors in  
evironment.rb or something and that prevented the server from  
correctly starting an loading rails.

did you change anything in environment.rb or another config file?
