我们正在运行一个带有大量请求（每分钟400个请求）的rails应用程序，其中3个webnode运行nginx和乘客。

然而，在过去的几天里，我们经历了几次崩溃，造成500错误。在nginx错误日志中找不到任何内容。 rails日志提供了一个相当不具描述性的错误消息，我希望你们中的一些人可以帮助我追踪：

ArgumentError: uncaught throw {:__recursive_key__=>true, 20687660=>true}

似乎在应用程序中发生了所有不同的地方，除非不需要数据库查询。然而，我们的数据库似乎很健康，在连接，内存和CPU方面有很多容量。

希望有人能给我一个如何解决这个问题的线索。

谢谢:-)

感谢您的建议:-)

异常会定期抛出 - 但它似乎只在数据库调用上（ - 在show_custom_pickup_identifier中？它只进行简单的AR查询）。所以我追踪它 - 我们认为我们发现了AWS RDS IOPS限制中的问题。在应用了更多的存储空间（因此更多的IOPS）之后它似乎已经消失了 - 至少今天:-)如果亚马逊有一个明确的指标我们已经超出IOPS（!!）那将是很好的..

因此，现在我们将指出这将永久解决问题： - ）
