I’m migrating an old Rails App to a new server, I think I’ve got most  
of my issues worked out so far. But…

When I run script/server --trace in the app I get the following  
output… and I have no clue what to do or even where to look… Any  
guidance or assistance would be greatly appreciated.

script/server --trace  
=\> Booting WEBrick…  
server: invalid option: --trace

Thanks in advance for any guidance/assistance.

yup, definitely not there… doh.

ok, so I ran script/server without the trace and I get this

=\> Booting WEBrick…

and then it comes back to the command prompt. It doesn’t start the  
app…? I was trying to use trace to see why.

Is there any way to troubleshoot this?
