Capistrano not restarting

Capistrano is deploying cold, deploying updates and uploading the symlink fine. It will not however restart.

I notice that permission is denied on the /script/process/reaper file. I have found a suggestion implying the file needs updated permissions. Does anyone have experience with this?

As an updated answer, for Capistrano 3 running on Passenger here is what I currently do:

task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # If your tmp folder does not exist yet, uncomment the 
      # line below to create it.
      # execute :mkdir, "#{File.join(current_path,'tmp')}"
      execute :touch, "#{File.join(current_path,'tmp','restart.txt')}"
    end
end

What is your deployment environment? With Passenger (Apache) I have something like:

  task :restart, :roles => :app, :except => { :no_release => true } do
    run "touch #{current_path}/tmp/restart.txt"
  end

They have their own support forums, maybe you should try there. http://groups.google.co.uk/group/capistrano/

Rails 2.3 no longer ships with the old reaper scripts. http://www.capify.org/index.php/How_to_use_Capistrano_with_Rails_2.3
