我正面临此处报告的确切问题：https://github.com/bitly/oauth2_proxy/issues/316
（从问题说明中，罪魁祸首被确定为 Kubernetes，在此论坛上发布查询。请告知我是否应该在其他论坛上发布）。
请求专家就我应该考虑调试/修复此问题的可能领域提供建议（已尝试启用 coreDNS 日志 - 未看到任何错误报告）
以下是我的 kubernetes 部署的详细信息：
版本：k3s 版本 v1.19.7+k3s1 (5a00e38d) 我有一个控制器 pod，它接收用户请求并在内部调用 oauth2-proxy pod API 来获取用户信息，如下所示：http://oauth2-proxy:4180/oauth2/userinfo。
请求率约为 250 个请求/秒。其中大约 1-2% 的请求会导致上述失败。
出现问题时的coreDNS指标如下：
