I’m in the process of moving an old Rails app to a new server and i  
can’t seem to get mongrel to start.

I issue the command:  
mongrel\_rails start

and I get this:  
\*\* Starting Mongrel listening at 0.0.0.0:3000  
\*\* Starting Rails with development environment …

I should note that this app is Ruby V 1.8.4 and Rails V 1.1.6 and  
Mongrel V 0.3.13.3

Thanks in advance for any assistance or guidance you may be able to  
provide.

It likes that you don’t have a ruby-debug gem (perhaps you forgot any  
“debugger” in your app).  
Try installing it: gem install ruby-debug
