Hi,

Just finished installing RoR on my brand new linode Ubuntu 9.04 VPS  
using  
following guides:  
[http://library.linode.com/web-frameworks/ruby-on-rails/installing-ruby-on-rails-with-apache](http://library.linode.com/web-frameworks/ruby-on-rails/installing-ruby-on-rails-with-apache)  
[https://help.ubuntu.com/community/RubyOnRails](https://help.ubuntu.com/community/RubyOnRails)

However, when I click on “About your application’s environment” I get  
following error:

Passenger encountered the following error:

The application spawner server exited unexpectedly  
Exception class:Passenger::Railz::ApplicationSpawner::ErrorBacktrace:

Any ideas please?

Thanks for reading.

I’ve got absolutely the same problem, but with 9.10, following the same  
guide on linode library.

Yep, I even tried restarting the whole server and it didn’t help.

There’s no real error in the OP. Are you sure your message states the  
exact same? What does the rest of your server setup look like?

I’ve found similar reports with no real error messages on the net, but  
those problems appear to be caused by memory limits and such. Could  
that be a problem on your setup?

Uh now I feel really stupid, it seems that I didn’t check the whole log,  
it is pretty different

anyway, I have set up virtual machine with 512MB RAM, 8GB HDD and the  
only thing that is runnig there is Apache, Mysql and Passenger, so I  
guess there is no problem with memory
