 hexa | we generally notice extremly long running builds and kill/poke | 11:20:02 |
| hexa | they are fairly rare, so it has not been a huge problem | 11:20:19 |
| hexa | and having some visiblity is better than ignoring them | 11:20:36 |

 mynacol | Were all the builder very busy the last hours? All the rusty-v8 builds for deno 2.7.13 failed, almost all on timeouts. At that build point in the logs, the major compilation work happens without any log output, but that should only take 30 min at max (more like 20 min IME). Maybe restart these jobs and/or increase the timeout for that derivation?

| hexa | they all get stuck at temporal_capi | 14:23:36 |
| hexa | so I suspect silent timeout | 14:23:42 |
| hexa | ^ | 14:23:49 |
| hexa | are our builders busy? yes, generally they are. | 14:24:06 |
 leona | and they run not on big-parallel, that means very few cores. Compile likely takes longer than you think. | 14:24:15 |
| hexa | normal builds get 2 cores | 14:24:20 |
| mynacol | Ahh, that probably explains it. Shall I move it to big-parallel? (it's still smaller than firefox/chromium) | 14:25:08 |
| mynacol | * Ahh, that probably explains it. Shall I move it to big-parallel? (it's still a lot smaller than firefox/chromium) | 14:25:19 |
| hexa | right now 59 packages have the big-parallel flag 🤔 | 14:26:34 |
 VladimÃr ÄŒunát | I'd say that if build without the flag takes hours and the flag speeds it up very significantly, we'd better add the flag. | 14:28:25 |

| mynacol | Or just increase the the timeout. (My compiles with 32 core somewhat older intel take 30 min for rusty-v8 and 1h for deno, and for comparison 1-2h (depending on pgo double-runs) on mullvad-browser) | 14:28:53 |

| mynacol | The funny thing is that the builds are at those points rather single-threaded (only one or two hefty crates). So I look into the timeout instead: https://github.com/NixOS/nixpkgs/pull/514057 | 14:51:28 |

 Ihar Hrachyshka | @mynacol:mynacol.xyz: increasing timeouts per package may not actually work because of a bug in nix, see https://github.com/NixOS/infra/pull/950 | 11:17:04 |
