问题:

我们该如何解决这个问题是我们在应用程序中遇到的问题还是Google平台的问题?

已采取的步骤:

  • 检查平台日志,没有VM迁移的迹象。
  • 检查了Google Cloud Status Dashboard,并且没有任何中断的迹象。

  • 问题的详细说明:

    10月16日(星期日)大约8:37:40 UTC,我们经历了网络和磁盘IO中断。这是一个摘要(有关详细信息,请参见下面的日志):
  • [08:37:40]:-我们的应用程序遇到了DNS问题
  • [08:37:43]:-sd 0:0:1:0:[sda]中止-在syslog
  • 中报告
  • [08:37:43]:-超过5分钟的内核“任务被阻塞超过120秒”消息
  • [08:43:10]:-sd 0:0:1:0:设备重置-在syslog
  • 中报告
  • [08:43:10]:-Google脚本中的三个错误(我认为与网络相关)
  • [08:43:11]:我们的应用程序恢复。

    最佳答案

    此错误通常是由 throttle 引起的。这可能是由于磁盘大小或磁盘I/O大量增加引起的。您应该尝试增加PD或using an SSD的大小以提高性能。
