I create delayed job to recurring run but it stop when working for 1 or 2 day later

I set it to run every 15 second as the following

    begin
      monitor_running_tasks
    ensure
      delayed_job = DelayedJob.where("handler like '%recurring_monitor%' and locked_at is NULL").first
      if delayed_job.nil?
        interval = 15.seconds.from_now
        self.delay({:run_at => interval}).recurring_monitor
      end
    end

After clean dirty data and tweak to 2 instance on 2 docker. It's not occured again.

I suggest it caused from memory leak and some thread issue
