System.ArgumentException, Message=Value does not fall within the expected range. Source=Grpc.Core

[M A]

"Value does not fall within the expected range exception" is thrown after around 63 asynchronous grpc calls. I cant tell exactly of how the exception is thrown out of my code.

System.ArgumentException HResult=0x80070057 Message=Value does not fall within the expected range. Source=Grpc.Core StackTrace: at Grpc.Core.Internal.UnaryServerCallHandler`2.<HandleCall>d__4.MoveNext() in Grpc.Core.Internal\UnaryServerCallHandler.cs:line 58

I expected no error after an x amount of synchronous grpc calls

Are you able to give more details and an example of the calling code? Version of gRPC you are using?

If you think this a genuine bug then raise it in https://github.com/grpc/grpc-dotnet/issues
