-----------------------------------------
Assignee: (was: Florian Hockmann)
[~spmallette] The issue isn't resolved by the linked PR as that only results in
a more meaningful exception being thrown, but the underlying problem is still
open.
We'll need a proper repairing of closed connections in the background to
actually fix this in my opinion. I had worked on that some time ago, but didn't
have the time yet to finish it.

> Key: TINKERPOP-2288
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2288
> Project: TinkerPop
> Issue Type: Bug
> Components: dotnet
> Affects Versions: 3.4.1
> Environment: Gremlin.Net 3.4.1
> Microsoft.NetCore.App 2.2
> Azure Cosmos DB
> Reporter: patrice huot
> Priority: Critical
> Fix For: 3.5.0, 3.4.7
>
>
> I am using .Net core Gremlin API query Cosmos DB.
> From time to time we are getting an error saying that no connection is
> available and then the server become unavailable. When this is occurring we
> need to restart the server. It looks like the connections are not released
> properly and become unavailable forever.
> We have configured the pool size to 50 and the MaxInProcessPerConnection to
> 32 (Which I guess should be sufficient).
> To diagnose the issue, Is there a way to access diagnostic information on the
> connection pool in order to know how many connections are open and how many
> processes are running in each connection?
> I would like to be able to monitor the connections usage to see if they are
> about to be exhausted and to see if the number of used connections is always
> increasing or of the connection lease is release when the queries completes?
> As a work around, Is there a way we can access this information from the code
> so that I can catch those scenario and create logic that re-initiate the
> connection pool?
