problem with renderiong

I'm create scaffold for table people, than i remove action show like this
# POST /people # POST /people.xml def create

@person = Person.new(params[:person])
@person.create_datum(params[:datum])

respond_to do |format|
  if @person.save
    format.html { redirect_to :action => 'index' }
    format.xml  { render :xml => @person, :status => :created, :location => @person }
  else
    format.html { render :action => "new" }
    format.xml  { render :xml => @person.errors, :status => :unprocessable_entity }
  end
end

end

# PUT /people/1 # PUT /people/1.xml def update

@person = Person.find(params[:id])

respond_to do |format|
  if @person.datum.update_attributes(params[:datum]) && @person.update_attributes(params[:person])
    format.html { redirect_to :action => 'index' }
    format.xml  { head :ok }
  else
    format.html { render :action => "edit" }
    format.xml  { render :xml => @person.errors, :status => :unprocessable_entity }
  end
end

end

I create a new person on page 'new', then redirect to 'index' (on development)
When I run it into production (mongrel_rails + lighttpd) I'm going to go on blank page.

In log file this look like
