 Arian | Ah lol yeh | 00:15:07 |
| hexa | 🙂 | 00:15:08 |
| hexa | but why do those leak into the host, while most other crashes do not? | 00:15:58 |

| hexa | the number of crashes we see per day | 00:17:02 |
| hexa | * the number of crashes we see per day on a single builder | 00:17:08 |
| hexa | most have no corefile | 00:17:17 |
 @9lore:tchncs.de | Hi, just curious https://hydra.nixos.org/build/288757617 is this stuck? Will it timeout at some point? | 00:17:50 |
| Arian | I guess filtering to just the ones we're comm=nix-daemon makes sense | 00:17:52 |
| raitobezarius | In reply to @hexa:lossy.network
but why do those leak into the host, while most other crashes do not? cgroups setup | 00:18:07 |
| raitobezarius | (or I misunderstood your remark) | 00:18:21 |
| hexa | likely after 2 hours of silence | 00:18:29 |
| hexa | raitobezarius: the question was: why do some few have corefiles, but most do not, when we're all running them in cgroups | 00:19:13 |
| hexa | * raitobezarius: the question was: why do some few have corefiles, but most do not, when we're all running them in the build sandbox | 00:19:23 |
| raitobezarius | corefiles are pruned | 00:19:28 |
| hexa | yes, but even new crashes have none 😄 | 00:19:39 |
| Arian | Systemd deletes them after a while | 00:19:41 |
| raitobezarius | maybe the vacuum algorithm is weird | 00:19:53 |
| raitobezarius | also corefiles cannot always be obtained | 00:20:08 |
| raitobezarius | some crashes simply does not come with corefiles | 00:20:12 |
| hexa | yeah, I kinda expected it to be a sandboxing limitation that we get none | 00:20:30 |
| raitobezarius | https://man7.org/linux/man-pages/man5/core.5.html | 00:20:30 |
| hexa | would also be ridiculuous to store that many 😄 | 00:20:41 |
| Arian | PID namespace should isolate coredumps yeh | 00:21:15 |
| Arian | @raitobezarius:matrix.org: it's just a tmpfiles rule iirc. | 00:22:06 |
| Arian | Anyhow I guess core dumps in the build sandbox are less interesting. We're interested in coredumps of nix-daemon. Still weird they show up in the journal though | 00:23:07 |
