What steps can reproduce the bug?

I just try to run an hello world script in a arm64 docker container based on the latest alpine image.
docker run --rm -it --entrypoint sh oven/bun:alpine

// hello.js
console.log("Hello world !");

bun hello.js

What is the expected behavior?

Hello world !

What do you see instead?

I'm able to reproduce the issue on older versions of bun as well. Version v1.1.44 also has the same issue inside a container.

I'm pasting a webm video as well of the issue. Running Bun v1.2.3 with Alpine in Docker.

bun-1080p.webm

pakoito · 2025-03-28T10:58:07Z

Can repro on WSL 1 and Bun 1.2.7

whiter001 · 2025-04-02T01:47:41Z

There is an issue with Docker on CentOS involving versions 1.2.8. Small files seem to work fine, but a file of size 286408 reports this error. The problematic version is: CentOS Linux release 7.9.2009 (Core). Docker on Debian does not have this issue.

Thanks @whiter001, that is very helpful. This means its a bug here:

this is probably related to #18746. Does your linux kernel have statx ? is it greater than 4.11 ?

@pakoito you kernel is more recent, so it may be a different problem. You can get more information by using strace (eg strace bun repl)

dtinth · 2025-04-08T08:10:12Z

Contributing my strace.

My app is built into a Docker container and sometimes it gets deployed to a PaaS (in our case, Virtuozzo Application Platform which is based on OpenVZ).

When the built app is run, I get this error:

# bun dist/main.js 
error: Unexpected reading "/app/dist/main.js"

Bun v1.2.8 (Linux x64 baseline)

Result of uname -a:

# uname -a
Linux $hostname 6.1.0 #1 SMP Tue Jan 9 19:45:01 MSK 2024 x86_64 GNU/Linux

Despite kernel v6.1.0, I think this is still due to statx, according to this line:

statx(12, "", AT_STATX_SYNC_AS_STAT|AT_EMPTY_PATH, STATX_TYPE|STATX_MODE|STATX_ATIME|STATX_MTIME|STATX_CTIME, 0x7fff8f276b30) = -1 ENOSYS (Function not implemented)

I’m aware that Zig will target modern kernels, but this will impact people who build backends based on Bun that will get shipped as Docker container to be run on other's environment where we have no control over.

Workaround

Current workaround is to downgrade to Bun 1.2.2
