Jayanta Mondal commented on TINKERPOP-2288:
-------------------------------------------
[~Florian Hockmann] : That's a valid concern.
But, perhaps, what was unclear in my proposal was that we won't resize the
connection pool, but would rather replace any dead connection with a new one.
This way we will avoid any calls to AddRange() or TryRemove() of the
CopyOnWriteCollection class, thereby avoiding any resize and potential
concurrency issues. Do you think that might work?
Let me know, how your timeline looks, otherwise, I can start a pull request on
this.

> 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
>
> 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?
