Describe the bug
The build hangs.
swift build -c release --disable-sandbox
Building for production...
[28/31] Compiling NIOConcurrencyHelpers NIOAtomic.swift // hangs here
To Reproduce
Follow the steps here, I checked out Vapor 18.7.4
Expected behavior
The build is successful.
That looks like a transient issue at the SwiftPM level; a build hang like that isn't something the toolbox's own code can cause, especially not while it's still compiling NIO. Does this reproduce reliably?

Yes. Falling back to 18.7.2 produces a similar result
swift build -c release --disable-sandbox

Doesn't seem to be a resource issue.
Can you try running swift package update before swift build?
Can you try running
swift package updatebeforeswift build?
Tried this and now it reproducibly hangs here instead.

I can't reproduce this hang in Docker, though the build does take a noticeable amount of time. Most likely this is the same old memory issue in the linker; how much RAM is allocated to your droplet?
Falling back to 18.6.0 produces same result.
Swift version 5.9.2 (swift-5.9.2-RELEASE)
Target: x86_64-unknown-linux-gnu
Will fall back to swift version 5.9.1 which is what you guys use in your DigitalOcean walkthrough docs.

512MB
Still same issue with Swift 5.9.1.

or

How much RAM do you recommend?
Ah yeah, that's known to not be enough even with the linker improvements in 5.9, unfortunately 😕. If you bump to 1GB, that should resolve your issue.
Resolved. Thank you @gwynne
I probably should have mentioned more details about the stack. Apologies for that.
