Unable To Start Ruby On Rails App

[sgjava]

I was unble to start a Ruby On Rails App named "sgj". When I'm clicking on the "Run" icon to start my app, I'm getting the message:

The following ruby on rails app were start: sgj

but when I'm getting back to the previous page after starting the app, I'm seeing the app status is "Not Running" as was before starting the app. I've tried to reload the page as mentioned on the heliohost wiki but, this time also I'm seeing that, the app status was not changed. So I want to know that, how to change my app status?
