Hi,  
I’m getting “Page Cannot be Found” error. The funny (let’s call it funny  
🙂 ) is that is random.  
When I restart the server, I can log in into my web properly.  
After a few minutes and server “log in’s”, it shows “Page Cannot be  
found”

I checked the production.log, and it complains about  
ActionController::RoutingError:

How can i debug this error? Why is it random?  
Also, it surprise me, that the log says:  
“_Processing Base#index_” (instead of the name of the controller,  
AuthenticatorController)  
_ActionController::RoutingError (Recognition failed for  
“/authenticator/auth/”):_

thanks,

Jean

Here the logs:

Hi,  
just some other details of this annoying bug … I can replicate it by  
calling very often this url in the browser (in my local machine):

[www.mytestingweb.com/authenticator/auth/?usr=removed\_email\_address@domain.invalid&pwd=c253cb050f104af4af6b](http://www.mytestingweb.com/authenticator/auth/?usr=removed_email_address@domain.invalid&pwd=c253cb050f104af4af6b)

This URL will invoke the auth method in the authenticator class.  
It seems that when this is run repeatedly and often, it gets somehow to  
a collision or something than crash, giving the RoutingError.  
Mmmm is there any problem with mongrels when calling very often?  
collision? Mongrels have been working fine for me for this time … I  
don’t think that all of a sudden, there are collision problems.

any comment will be much appreciated,

regards,

Jean
