Exception monitoring failed

[paulomorgado]

Expected behavior

A memory dump is captured on a first chance .NET exceptions.

Actual behavior

ERROR]: Exception monitoring failed.

Steps to reproduce the behavior

Run any ASP.NET application that serves static files (dotnet new razor).

That will get this error when serving static content:

System.ArgumentOutOfRangeException:  (Parameter 'offset')
Actual value was 0.
   at Microsoft.AspNetCore.Http.SendFileResponseExtensions.SendFileAsyncCore(HttpResponse response, IFileInfo file, Int64 offset, Nullable`1 count, CancellationToken cancellationToken)
   at Microsoft.AspNetCore.StaticAssets.StaticAssetsInvoker.SendAsync(StaticAssetInvocationContext context)
   at Microsoft.AspNetCore.StaticAssets.StaticAssetsInvoker.Invoke(HttpContext context)
   at Microsoft.AspNetCore.Builder.StaticAssetDevelopmentRuntimeHandler.<>c__DisplayClass3_0.<<AttachRuntimePatching>b__0>d.MoveNext()
--- End of stack trace from previous location ---
   at Microsoft.AspNetCore.Routing.EndpointMiddleware.<Invoke>g__AwaitRequestTask|7_0(Endpoint endpoint, Task requestTask, ILogger logger)
   at Microsoft.AspNetCore.Authorization.AuthorizationMiddleware.Invoke(HttpContext context)
   at Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.Invoke(HttpContext context)
   at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddlewareImpl.Invoke(HttpContext context)

Try to capture the error:

# procdump -n 100 -e 1 -f ArgumentOutOfRangeException PauloMorgadoNet

Hi - Thanks for reporting this. Based on the output, I assume this is running in a containerized environment? Also, what distribution are you running?
