Asp.net IdentityServer 3负载测试失败

我们将IdentityServer 3与实体框架包一起用作持久层。使用Serilog进行跟踪/记录输出

我们目前使用的版本是2.6.0

当进行一些基本负载测试时，例如使用有效令牌向我们的api主机发出请求：

我们在日志中发现大量故障。我们正在使用的令牌是有效的，并且我们已经按照如下方式配置了LoggingOption

options.LoggingOptions.EnableHttpLogging = true;
options.LoggingOptions.EnableWebApiDiagnostics = true;
options.LoggingOptions.EnableKatanaLogging = true;
options.LoggingOptions.WebApiDiagnosticsIsVerbose = true; 

任何关于什么可能导致这种情况或如何进入日志记录以提供有关cuase的更多相关细节的指导都将不胜感激
