Googlebot keeps throwing MethodNotAllowed errors in Application#index

Hi guys,

Does anyone know how to solve this problem? As long as my app has lived, Googlebot (IP 66.249.68.199) brings up the ActionController::MethodNotAllowed error several times a week, saying "Only put requests are allowed." How is Googlebot even accessing Application#index (I assume this is the application controller), and why are only post requests allowed? Thanks.

Rails 2.3.2

What is the exact url that it is trying to access?
