I''m not sure if "controller.rb" is part of Rails or not. However, last night I decided to run RDoc on my entire Ruby tree to see what was there, and it stopped progressing while documenting "controller.rb". It turns out that the Rdoc thread or process had gotten up to about 450 MB on a 512 MB machine and was swapping its little brains out. Is this a memory leak somewhere, or is "controller.rb" just so big that you shouldn''t run Rdoc on it? -- M.
