[jira] [Comment Edited] (TINKERPOP-2148) "no connection available!"
is being thrown despite lots of free connections

I have never done a pull request to an open source project. Most likely it would take me a lot time to get everything right (especially on Windows). Considering the time constraints I believe it would be better if someone more experienced handles this. Although thanks for the offer!

> Key: TINKERPOP-2148
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2148
> Project: TinkerPop
> Issue Type: Bug
> Components: dotnet
> Affects Versions: 3.4.0
> Environment: Windows 10, C#, .NET Core, CosmosDB Graph
> Reporter: Zaoshi
> Priority: Minor
>
> I am submitting multiple graph queries in parallel but in some cases it starts throwing this exception:
> {{Gremlin.Net.Driver.Exceptions.NoConnectionAvailableException : no connection available!}}
> {{ at Gremlin.Net.Driver.ConnectionPool.GetAvailableConnectionAsync()}}
> {{ at Gremlin.Net.Driver.GremlinClient.SubmitAsync[T](RequestMessage requestMessage)}}
> When GremlinClient is initialized with \{PoolSize = 1, MaxInProcessPerConnection = 8} everything works fine, however, with \{PoolSize = 8, MaxInProcessPerConnection = 1} it starts throwing those exceptions even though this connection pool should have same throughput. I have tried to increase pool to \{PoolSize = 128, MaxInProcessPerConnection = 1} but GremlinClient started to fail even more.
