Hello,

I can’t start RoR if I put config.active\_record.observers  
= :users\_observer into my environment.rb file. Mongrel gives me this  
error:

\*\* Daemonized, any open files are closed. Look at tmp/pids/mongrel.

Any ideas? I got the latest version of restful\_authentication from  
github.

Best regards.
