我在同一个实例上出现了这个错误 20 次,然后在实例被杀死后它就消失了,因为处理了太多的顺序错误。我的代码没有进行任何更改,这是我唯一一次看到这种情况发生。

问题:

  • 我的代码中的什么类型的问题可能导致这种情况仅在某些情况下发生?我不知道从哪里开始寻找,因为我无法重现问题。
  • 有没有办法减少实例在被杀死之前允许的顺序错误的数量,这样如果再次发生就不会造成太大的破坏?

这是我从这个实例中获得的第一个日志(没有错误):

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.

这是此实例的下一个日志(第一个有错误):

在这两个日志之间有一个日志,其中创建了一个额外的实例(没有错误)。没有一个错误来自在第一个实例之后立即创建的另一个实例。由于处理了太多的顺序错误,它在第一个实例被杀死后开始成功处理请求。

我在部署代码后偶尔会看到此错误,并且重新部署通常会停止它。我知道,这没什么帮助,但希望这是谷歌很快会解决的问题。
