Jobs stopped in celluloid pool

Question

Im need to retrieve data for account in parallel. I use celluloid for that

my code

class Daemon

  def self.start
    loop do
       Account.all.each do |acc|
         unless Celluloid::Actor[account.name]
          supervise_as(account.name, account)
          Celluloid::Actor[account.name].async(:perform)
        end

        sleep 10.minutes
      end
    end

    def initialize(account)
      @account = account
    end

    def perform
      loop do
        do_request

        sleep 10
      end
    end
  end

On start it always do parallel request for all members(bob, alice, etc). But after some time it makes requests only for one user (alice for ex.)

PS in do_request used self-made redis queue and in Celluloid::Actor.registed all accounts exists
