Delayed job don't release memory after jobs completed. It's same issue #1015 https://github.com/collectiveidea/delayed_job/issues/1015

Kill worker delayed job if it's eat more memory (LIMIT_MEMORY = 1G) after jobs completed

  class Job
    def perform 
      ....
    end
 
    def after(job)
      if (`ps -o rss= -p #{Process.pid}`.to_i / 1024) > LIMIT_MEMORY
        `kill -15 #{Process.pid}`
      end
    end
  end
