@candlerb Thank you very much for this in-depth explanation! I haven't had time to try it out yet (and looking at my calendar, I won't have time for a while),...

We've encountered almost the same problem (also with PostgreSQL). But in our case it's happening on macOS. It's a rather simple Vapor application that (after some time) starts failing queries....

I've implemented a little workaround to get working connections. It's not perfect but seems to do the job in our case. ```swift private let connectionClosedErrNos: Set = [ ECONNRESET, //...

@HashedViking To be honest, I was too lazy to port the fix to Vapor 4. Instead I've added this snippet to my `configure.swift`: ```swift // Schedule DB reinitialization every night...

We encountered the same problem in [this PR](https://github.com/CocoaLumberjack/CocoaLumberjack/pull/1146#issuecomment-659322158) in CocoaLumberjack after we've switched from Travis + Danger.ruby to GitHub Actions + Danger.swift. @f-meloni thank you for providing the pre-built docker...

@f-meloni I see. Thanks for explaining! Haven't tried myself, but according to this [help page](https://docs.github.com/en/packages/using-github-packages-with-your-projects-ecosystem/using-github-packages-with-github-actions#installing-a-package-using-an-action), it should be possible to use GitHub Packages together with GitHub Actions... Is there a...

@f-meloni Apparently the problem is not using GitHub Packages with GitHub Actions in general, but specifically using a Docker GitHub Package the run-image for a step (with the `using:` keyword):...

@fwal I'm not sure this is Xcode related. The same `swift test` runs fine on Linux when using this action to setup Swift. Using [setup-xcode](https://github.com/maxim-lobanov/setup-xcode) to select an Xcode version...

Can you please fill out the issue form? This issue is missing the necessary information for us to be able to even take a guess at the underlying problem!

Thanks. This seems to me like a Carthage issue. I don't think we can do much here.
