Ruby rTurk无法从Amazon Mechanical Turk获取结果

我遇到了一个非常奇怪的问题。我能够提交一个点击亚马逊机械土耳其人正确。我有一个cron，它不断检查是否有任何工作准备好接受审查。然而，当一项工作完成时，我没有收到它，但是点击被处理，在函数内部做了什么来检查它。奇怪的是，这个问题并非总是发生，而是经常发生

这是查看点击的函数代码：

def self.review_hits
hits = RTurk::Hit.all_reviewable
p "HITS"
p hits
puts "REVIEWABLE HITS: " + hits.count.to_s
hits_results = {}

unless hits.empty?
  hits.each do |hit|
    puts "IN EACH HIT"
    p hit
    results = []
    hit.expire!

    # Get results for each HIT assignment
    hit.assignments.each do |assignment|
      # Check if the assignmment has been submitted. It can be the case where the maximum waiting time
      # for the job to finish expired and there remain assignments that are not submitted
      if assignment.status == 'Submitted'
        p "STATUS 1"
        p assignment.status
        temp = {}
        temp[:worker_id] = assignment.worker_id
        temp[:answer] = assignment.answers
        p "STATUS 2"
        p assignment.status
        assignment.approve!
        results << temp
      end
    end

    begin
      hit.dispose!
    rescue
    end

    hits_results[hit.id] = {}
    hits_results[hit.id][:results] = results
  end

  # Let Rails know that there are new results
  AmazonTurkHit.store_results(hits_results) 
end

结束

因此，puts可查看命中数：为0，但命中数已释放。有人知道为什么吗？

经过一段时间的疯狂思考，我意识到这个问题非常愚蠢。。。我有两个系统实例在运行，一个在生产中，一个在暂存中，但都使用相同的AWS帐户，所以有时命中被另一个系统捕获…：
