One app hangs loading Rails and another doesn't; suggest str

Rails
1

When I enter “ruby script/server” in one directory, the result is:

C:\work\ratingasp01>ruby script/server
./script/…/config/boot.rb:29:Warning: require_gem is obsolete. Use
gem instead.
=> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000
** Starting Rails with development environment…

The CPU utilization on Ruby hovers at 90% and the Mongrel server is
not responsive to a browser.

If I switch to a sister app/directory, the result is:

C:\work\astro1>ruby script/server
./script/…/config/boot.rb:28:Warning: require_gem is obsolete. Use
gem instead.
=> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000
** Starting Rails with development environment…
** Rails loaded.
** Loading any Rails specific GemPlugins
** Signals ready. INT => stop (no restart).
** Mongrel available at 0.0.0.0:3000
** Use CTRL-C to stop.

This version is responsive and uses a tiny amount of CPU.

Looks like Mongrel or Rails is looping. Trying Webrick didn’t solve
the problem. Please suggest a strategy I can use to determine why I
hang in the “Rails loaded.” step.

My versions are:

C:\work\ratingasp01>ruby --version
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]

C:\work\ratingasp01>rails --version
Rails 1.2.3

I’m on Windows XP SP2. Could I be running a different Rails in the
“ratingasp01” folder?

Thanks,

Carl
