Hi, for the past few days, my site goes down a couplle times a day and  
when it does I get an error like that below in my prod.log. If I reload  
the main index page a few times the app eventually recovers and loads  
properly but I’d like to know what is causing this to happen in the  
first place and how to resolve it. Can anyone decipher this error here?  
I have changed nothing with my app for a couple months so I don’t know  
why it would start happening now. Thanks.

It might help to see what’s in that castle.rb file.

Hi Rob,

> It might help to see what’s in that castle.rb file.

not much actually.

class Castle \< ActiveRecord::Base  
has\_many :cpictures, :dependent =\> :destroy, :order =\> ‘vieworder’  
has\_one :highlighted, :class\_name =\> ‘Cpicture’, :order =\>  
‘highlighted DESC’

```
acts_as_cache_clearer

acts_as_ferret :store_class_name => true

```

def to\_param  
“#{id}-#{castle\_name\_en.gsub(/[^a-z1-9]+/i, ‘-’)}”  
end

end

Couple of suggestions that may fix your problem.

1. Make sure that you have no modules, classes defined by same name  
castle.rb.
2. If your module depends upon some of the external libraries, either  
from RAILS\_ROOT/lib directory or from standard ruby PATH, make sure  
that you explicitly require that library in environment.rb file.
