iis运行后
系统的异常日志信息:
Category: Microsoft.AspNetCore.Server.IIS.Core.IISHttpServer
EventId: 0
RequestId: 8000000d-0002-fb00-b63f-84710c7967bb

ActionName: SU.WebApi.Controllers.PreventiveControlController.InvestigationReport (SU.WebApi)
Increasing the MaxRequestBodySize conflicts with the max value for IIS limit maxAllowedContentLength. HTTP requests that have a content length greater than maxAllowedContentLength will still be rejected by IIS. You can disable the limit by either removing or setting the maxAllowedContentLength value to a higher limit.
当次异常信息抛出不久后.net rumtime貌似停止了工作:

按照这个错误信息
System.InvalidOperationException: Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.
将 Dictionary 改为 ConcurrentDictionary shi'sh
是要修改程序代码吗?
@少年Dev: 是的

我查看了下好像D盘没这个路径哦
我猜服务器可能陷入这样一种情况，即 EF 在执行 linq 语句时同时更新和写入某种数据，然后让 Dictionary 陷入奇怪的状态，但我不知道如何防止这种情况以及真正的问题在哪里。这是 .NET 错误还是我自己的错误？
