Hey @canuc and @razielgn

I think #285 actually solves this. Would either of you be willing to test your code with the version of that PR?

[razielgn]

Hello, yes I'm going to deploy this patch today and let it run for a few days. I think by Monday it'll be clear. Thank you!

[canuc]

This is amazing! thanks so much!!!

Hi @canuc

This sounds like a bug. But you're not giving me much context to reproduce this. What version of k8s is this? What is the code that leads to this?

Thanks

[razielgn]

I'm also having this issue, using version 2.4.1 (mint 1.5.1). It happens every 3/4 days, sometimes multiple times in a single day.
What I have is a cronjob via Oban that periodically does

K8s.Conn.from_service_account()
|> K8s.Client.run(K8s.Client.list("argoproj.io/v1alpha1", "workflow", namespace: "argo-workflows"))

Here's the stacktrace:

** (exit) exited in: GenServer.call(#PID<0.292039.0>, {:recv, #Reference<0.4064860026.2373451778.104924>}, :infinity)
    ** (EXIT) shutdown: :closed

Let me know if I should provide more info, thanks.

Sorry, I totally forgot about this issue. It reached me while on vacation. I have an idea of what could be the problem, but I need a quiet moment to wrap my head around it.

Note to self: Double check the meaning of the type option of Mint.open?() - docs don't seem obvious right now.

[mruoss]

@razielgn all quiet so far?

[razielgn]

All quiet so far!

[mruoss]

Nice. Thanks for testing it. I will merge and release.

[razielgn]

Thanks!
