Florian Hockmann commented on TINKERPOP-2090:
---------------------------------------------
{quote}However after updating to 3.4.0, I am getting errors in that test. I
end up getting WebSocketExceptions with a messages saying that the operation
completed successfully. Any idea why that would be the case?
{quote}
Not from the top of my head, no. But that really sounds like a separate issue.
So, could you create a new issue for that and provide a stack trace there and
ideally a good description or even code example (if it's not too long) of what
you're doing when the exception occurs?

> Project: TinkerPop
> Issue Type: Bug
> Components: dotnet
> Affects Versions: 3.4.0
> Environment: .NET Core 2.1.5
> Microsoft Azure
> Reporter: Saber Karmous
> Priority: Critical
>
> .NET Core 2.1.5
> Gremlin.NET 3.4.0-rc2
> We're using the latest RC of the Gremlin client. And we have a gremlin client
> that's being injected as a singleton through out IoC container. After running
> the backend for a day or two it keeps throwing System.IO.IOExceptions. If we
> restart the application it works again.
> We use Polly for out retry strategy, and retrying for 9 times. But it keeps
> failing.
> I added the stack trace below. Reproducing is a bit of a pain in the behind,
> you have to wait for a day or two for the exception to occur.
