Sidekiq looking for en.yml file in older capistrano release - ruby-on-rails

Question

I am running sidekiq in production and I deploy my app using capistrano. While processing background job, I am getting following error
I18n::InvalidLocaleData: can not load translations from /path/to/folder/releases/20160904153949/config/locales/en.yml: #<Errno::ENOENT: No such file or directory # rb_sysopen - /path/to/folder/releases/20160904153949/config/locales/en.yml>.
release 20160904153949 is old and has been deleted. I am wondering why sidekiq is still looking into older release.
Below is how my deploy.rb file looks like:
# config valid only for current version of Capistrano
lock '3.4.0'
set :application, 'app_name'
set :repo_url, 'git#github.com:reboot/app_name.git'
# Default branch is :master
set :branch, 'master'
# Default deploy_to directory is /var/www/my_app_name
set :deploy_to, '/path/to/app'
set :use_sudo, false
set :bundle_binstubs, nil
# Default value for :scm is :git
set :scm, :git
# Default value for :format is :pretty
set :format, :pretty
# Default value for :log_level is :debug
set :log_level, :debug
# Default value for :pty is false
set :pty, true
# Default value for :linked_files is []
set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml')
# Default value for linked_dirs is []
set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'public/assets')
# Default value for default_env is {}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }
# Default value for keep_releases is 5
set :keep_releases, 5
set :keep_assets, 3
after 'deploy:publishing', 'deploy:restart'
namespace :deploy do
task :restart do
on roles(:app) do
execute :touch, release_path.join('tmp/restart.txt')
end
end
end
Below is how my Capfile looks like
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
require 'capistrano/sidekiq'
# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
sidekiq stop/start is handled by capistrano/sidekiq gem. My app gets deployed fine. Problem is that sidekiq is looking into wrong release for required file.
Also I don't have sidekiq.yml file at this stage. My app is small so never created yml file for it.
Ruby: 2.3.0p0,
Rails: 4.2.5,
nginx/passenger combination,
Capistrano 3.4

Answer 1

Ok so I solved the problem by following these steps:
kill process of sidekiq pkill sidekiq
deleted sidekiq pid file from /path/to/app/current/tmp/pid/
started sidekiq using cap sidekiq:start, this will create pid file
finally deploy my app ( this process will restart sidekiq again)
Everything worked find after that.
