Describe the bug

I see this exception in the Windows event viewer logs under ".NET Runtime". Level is "error".
Category: Microsoft.AspNetCore.Server.HttpSys.MessagePump
EventId: 5

Failed to accept a request.

Exception:
Microsoft.AspNetCore.Server.HttpSys.HttpSysException (1229): An operation was attempted on a nonexistent network connection.
at Microsoft.AspNetCore.Server.HttpSys.AsyncAcceptContext.GetResult(Int16 token)
at Microsoft.AspNetCore.Server.HttpSys.MessagePump.ProcessRequestsWorker()

Is this indicative of client side disconnect? If so, can its level be turned down from "error"?
