Rails App Error with lighttpd

I have the same exact configuration on a dev machine and a production
machine. When I put it on a different production machine, I get:

#{RAILS_ROOT}/vendor/rails/railties/lib/fcgi_handler.rb:150:in 

process_request' #{RAILS_ROOT}/vendor/rails/railties/lib/fcgi_handler.rb:54:inprocess!’
#{RAILS_ROOT}/vendor/rails/railties/lib/fcgi_handler.rb:53:in
each_cgi' /usr/local/lib/ruby/site_ruby/1.8/fcgi.rb:597:ineach’
/usr/local/lib/ruby/site_ruby/1.8/fcgi.rb:597:in each_cgi' #{RAILS_ROOT}/vendor/rails/railties/lib/fcgi_handler.rb:53:inprocess!’
#{RAILS_ROOT}/vendor/rails/railties/lib/fcgi_handler.rb:23:in
`process!’
/home/vhosts/ekreg.com/rails/three19/public/dispatch.fcgi:24

Does this ring any bells with anyone?

Thanks…
