 hacker1024 | For some reason my NixOS ISO jobs (from system.build.isoImage) are timing out after two hours. I cannot find any reference to this limit in the Nix documentation or Nixpkgs, and I have not got anything resembling a value for two hours in my Nix or Hydra configuration. Does anyone know what is causing this? None of my other jobs that last longer than two hours time out. | 08:51:53 |

 K900 (deprecated) | It's probably in meta.timeout on the derivation itself | 08:53:41 |

It's probably in meta.timeout on the derivation itself I checked in the REPL and in Nixpkgs, that doesn't seem to be the case | 09:02:54 |

 vcunat | IIRC there are two kinds of timeout. The other one is for max. silent time (no new logs). | 06:28:23 |
| vcunat | .meta.timeout is just an override, for some value configured I think. | 06:30:10 |
| vcunat | * .meta.timeout is just an override, for some value configured in Hydra or Nix I think. | 06:30:17 |
| vcunat | Yeah, man nix.conf shows even a few more kinds of timeouts | 06:31:26 |
| hacker1024 | Yep, the problem is that both my timeout and my max-silent-time is set to zero in nix show-config, and there's no mention of a timeout in hydra.conf. | 06:31:59 |

Thanks for the tip | 06:33:16 |
| hacker1024 | Oh, that default is actually in the manual. My bad. | 06:34:20 |
| hacker1024 | I suppose it makes sense to set it in Hydra (nix.conf doesn't really make sense across multiple build machines), but that default is pretty low. | 06:35:20 |
| vcunat | Two hours without any log line seems pretty suspicious to me. Could be e.g. thrashing due to low RAM. | 07:54:17 |

Two hours without any log line seems pretty suspicious to me. Could be e.g. thrashing due to low RAM. The SquashFS compression takes a long time, and there's nothing to be outputted while that's happening. I'm only using a free-tier Oracle Cloud VM with 4 ARM cores, so it can take a little longer than normal when other derivations are building at the same time. | 07:57:50 |

 artturin | maybe making this https://github.com/NixOS/nixpkgs/blob/bbfcab42fd6f93f1f45fdd50544735edf79ffe90/nixos/lib/make-squashfs.nix#L25-L29 dependant on stdenv.buildPlatform.is32bit would help? | 20:29:23 |

| artturin | I introduced the limit in https://github.com/nixos/nixpkgs/commit/eea6baad509b24c9137fd9d97fd3ae9392cf34de | 20:30:20 |
