This god recipe keeps starting up sidekiq processes every 5~10 seconds, but why?

sidekiq.god

God.watch do |w|
  pid_file = "#{RAILS_ROOT}/tmp/pids/sidekiq.pid"
  
  w.name = 'sidekiq'
  w.interval = 30.seconds
  w.start = "cd #{RAILS_ROOT} && RAILS_ENV=#{RAILS_ENV} bundle exec sidekiq -C #{RAILS_ROOT}/config/sidekiq.yml -P #{pid_file} -e #{RAILS_ENV} -L #{RAILS_ROOT}/log/sidekiq.log -d"
  w.stop = "bundle exec sidekiqctl quiet #{pid_file}"
  w.start_grace = 10.seconds
  
  # restart if memory gets too high
  # w.transition(:up, :restart) do |on|
  #  on.condition(:memory_usage) do |c|
  #    c.above = 200.megabytes
  #    c.times = 2
  #  end
  # end
  
  w.uid = 'bart'
  w.gid = 'developers'
  
  # determine the state on startup
  w.transition(:init, { true => :up, false => :start }) do |on|
    on.condition(:process_running) do |c|
      c.running = true
    end
  end
  
  # determine when process has finished starting
  w.transition([:start, :restart], :up) do |on|
    on.condition(:process_running) do |c|
      c.running = true
      c.interval = 5.seconds
    end
    
    # failsafe
    on.condition(:tries) do |c|
      c.times = 5
      c.transition = :start
      c.interval = 5.seconds
    end
  end
  
  # start if process is not running
  w.transition(:up, :start) do |on|
    on.condition(:process_running) do |c|
      c.running = false
    end
  end
  
  # New release by capistrano? Restart sidekiq!
  w.restart_if do |restart|
    restart.condition(:restart_file_touched) do |c|
      c.interval = 5.seconds
      c.restart_file = File.join(RAILS_ROOT, 'tmp', 'restart.txt')
    end
  end
end

2 year later I'l throw an answer here.

Your process has no restart condition, only c.start and c.stop. Pretty sure by default, a god restart command will just call start on its own and not a combination of the 2 (thus spawning a new process).

The reason for the restart every 5 seconds is the restart condition at the cotton. The restart_file_touched will always be true, and you've set an interval to run the command every 5 seconds.
