Consistent but random "signal 6 (Aborted)" errors with remote builder on version 2.4 #5270

Open jasoncarr0 opened 3 years ago

jasoncarr0 commented 3 years ago

Describe the bug

Several packages appear to be failing with a consistent error when using a remote builder: /nix/store/gpk9ljdjhnymw4gkxf46db2rhfc09gad-sshd.conf-validated.drv' failed due to signal 6 (Aborted)

The only workaround is to manually disable the remote builder before building one of these packages, such as by modifying /etc/nix/machines or changing the system config (which is hard to do when you can't build your system due to this issue!). It does not appear to be isolated and has appeared simultaneously for multiple packages after upgrading to a recent nixpkgs.

Other packages I've seen it on: (most notably steam doesn't require any special configuration or a system module like the others) /nix/store/ma1df4gvcc5p53mh73crlb1qkfsjpwpx-font-bh-100dpi-1.0.3.drv /nix/store/njf5cp889cvbh56y6fr9zcdsk3cr3v0k-steam-original-1.0.0.70.drv

These packages fail 100% of the time, at an apparently random point in the build

Steps To Reproduce

  1. Enable a remote builder, I have: 
    nix.buildMachines = [ {
hostName = "example.lan";
system = "x86_64-linux";
maxJobs = 1;
speedFactor = 2;
supportedFeatures = [ "nixos-test" "benchmark" "big-parallel" "kvm" ];
mandatoryFeatures = [ ];
}] ;
  2. Build one of a few packages, such as steam, most easily, or also enabling fonts or sshd
  3. They should error at a random time with the above error

Expected behavior

The packages build successfully, such as via being built on the local machine.

nix-env --version output

Full nix-info as I started this at nixpkgs

Local machine:

$ nix-shell -p nix-info --run "nix-info -m"

Also, remote builder:

$ nix-shell -p nix-info --run "nix-info -m"
  - system: `"x86_64-linux"`
 - host os: `Linux 5.10.52, NixOS, 21.11pre305786.aaf9676fbb7 (Porcupine)`

dnr commented 3 years ago

I hit this yesterday. It was happening reliably when using Nix 2.3.16 on the local side and Nix 2.4 on the remote side (both on aarch64). Downgrading the remote to 2.3.16 fixed it completely.

I got core dumps and was able to get a backtrace with gdb. I can attach some if anyone thinks it would be helpful, but I suspect just the 2.3.16→2.4 combination should be enough for anyone to reproduce it.

mweinelt commented 2 years ago

I'm hitting this consistently with home-assistant, which has a huge number of leaf packages. I saw this happening as soon as I upgraded my client to nix 2.4, when the remote builder was still 2.3.16. I upgraded the remote builder to 2.4 in the meantime, but builds are still failing with SIGABRT.

zopieux commented 2 years ago

Got hit by this too, reproducibly. Remote builder is 2.4, local builder is 2.3.16. Using 2.3.16 on the remote fixes it.

mweinelt commented 2 years ago

Probably related to #4664.

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

mweinelt commented 2 years ago

Can reproducibly see SIGABRT on my remote builder using nix2.6pre20211217 when building home-assistanton staging.

Still happens with 2.6 and 2.3 when remote building across architectures.

Ericson2314 commented 2 years ago

Thanks for the backtrace. We have an exception raised during a destructor.

coreyoconnor commented 2 years ago

Took me a bit to notice this was happening: I had a retry loop mitigating the issue. That stopped helping recently.

I was able to reproduce with 2.8 and 2.9 on both the builder and the requester.

Fixing the nix version to 2.3 for both avoided the issues.
