#Dagger tries calling docker system migrate with podman installed

System Details:
OS: ubuntu:24.04
Arch: AMD64
OCI Engine: podman
Dagger: dagger v0.18.3 (docker-image://registry.dagger.io/engine:v0.18.3) linux/arm64

In nth run: it starts by giving:

! connection error: desc = "error reading server preface: command [docker exec -i dagger-engine-v0.18.3 buildctl dial-stdio] has exited with exit status 255, make sure the URL is valid, and Docker 18.09 or later is installed on the remote host: stderr=Error: OCI runtime error: crun: the container `024d005d95e7830b8c74136205abeec74eb4c01051e2f485a05bda81f2fbb9f6` is not running\n"

Then possibly with n+1 or 2 runs it crashes
Stacktrace: File attached.
Logs from CI: File attached.

In logs it said docker system migrate, by docker it means podman

Its a little hard to reproduce.

Does this have to anything with System CPU and Mem?

@solemn leaf what does docker inspect dagger-engine-v0.18.3 say?

#

I'd assume the engine is maybe being killed for some reason?

#

OOM maybe?

#

Whats OOM? Yes, its possible. I was running on 2GB Ram and 2CPUs.
Then I upgraded it, but only ran once.

This is from the same machine but different container and upgraded spec

@solemn leaf mind sharing the output of dagger logs dagger-engine-v0.18.3as well? 🙏

@solemn leaf looks like the engine was shut-down gracefully

#

according to the logs

#

so something is telling docker to stop that container

#

can you reproduce it consistently?

solemn leaf
#

can you reproduce it consistently?
No, its not frequent. I'll test it more and try to pin down when its happening.

PS: the OCI engine that I am running is podman and not docker
