> CloseAndRemoveAllConnections bubbles up System.Net.Http.WinHttpException and doesn't recover
> --------------------------------------------------------------------------------------------
>
> Key: TINKERPOP-2043
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2043
> Project: TinkerPop
> Issue Type: Bug
> Components: dotnet
> Affects Versions: 3.4.0
> Environment: Gremlin.Net 3.4.0-rc1
> Microsoft.NetCore.App v2.0
> Reporter: Sami
> Priority: Critical
>
> We have a .Net Core web api with an Azure Cosmos db backend.
> Our data access layer calls _gremlinConnection.Client.SubmitAsync<dynamic>(query) using a singleton gremlin connection. This has worked well except when the API is called with many parallel web api requests. The endpoints that we provide make around 5 gremlin calls (some to read, some to write cosmos db edges).
> During performance testing we noticed System.Net.Http.WinHttpException
> Looking into the issue, we found that NrConnections was at 96 and the stack trace showed that Gremlin.Net called ConnectionPool.CloseAndRemoveAllConnections.
> We would expect that Gremlin.Net would recover after a call to CloseAndRemoveAllConnections and finish its "Client.SubmitAsync" call but instead it bubbles up the System.Net.Http.WinHttpException and immediately following calls to our API failed with the same System.Net.Http.WinHttpException.
>
> Would you agree that Gremlin.Net's ConnectionPool.CloseAndRemoveAllConnections should recover on its own and +complete+ its Client.SubmitAsync call or do you expect the consumer of Gremlin.Net to provide some work-around? If so, how can the pool be re-initiated or reset from outside of the Gremlin.Net library?
>
> Here is the stack trace. Please note that we are ready for a release and this is holding us back. By the way, we do use Gremlin.Net 3.4 RC1 but 3.3.3 also proved to have the same issue.
