For a few months now, we have been seeing these dozens of these warnings in /logs on a daily basis:

Unicorn worker received USR2 signal indicating it is about to timeout, dumping backtrace for main thread

As we usually run on stable, I assumed they would eventually go away when we jumped into the next major version which we did this week. We are now on 3.4.1, but the errors continue.

I’m not sure if they may be related, but we are also seeing two classes of errors (not warnings), intermixed, although less often:

These may be related with this, but in my case they seem to persist. And, as mentioned there, the logs do seem to get truncated sometimes.

And what all this looks like in /logs:

Any clues on what might be causing these? Can I prove any other info?

Je rencontre la même erreur sur notre instance lors de la publication/modification/approbation d’un sujet avec un contenu Markdown très spécifique. Il se charge pendant un moment puis renvoie une erreur interne du serveur.

L'image montre une boîte de dialogue avec le message « Erreur interne du serveur », ainsi qu'un bouton « OK ». (Légendé par l'IA)

Pour information, nous avons également vu des rapports sporadiques d’utilisateurs avec des erreurs similaires lors de la modification de certains messages (généralement assez longs, bien que pas proches de la limite), où de minuscules modifications au texte semblent surmonter l’erreur (anecdotiquement : ajouter un point, remplacer un tiret, etc.). Je n’ai pas encore trouvé d’étapes reproductibles car j’en entends généralement parler uniquement lorsqu’une personne a trouvé le « truc magique ».

J’ai également remarqué ces avertissements. Lorsqu’ils commencent, ils peuvent se répéter plusieurs fois en une heure environ, puis s’arrêter. Jusqu’à la prochaine fois. Je jurerais que nous ne les avions pas il y a quelques jours.

Sur quelle version êtes-vous, @icaria36 et @Indra ? Nous sommes sur stable, mais je me demande si cela se produit également dans tests-passed.

Nous sommes sur la version 3.5.0.beta3-dev (3f353a726b).

Je pense avoir trouvé quelque chose qui est probablement lié à cela et qui pourrait fournir plus d’indices sur la source du problème. Cela devient un peu long, alors soyez indulgent.

J’ai remarqué aujourd’hui que j’ai quelques tâches sidekiq qui échouent et qui sont en cours de nouvelle tentative depuis au moins une semaine avec la même erreur que dans les /logs.

Dans la console, si je réessaie de rebaker ce post spécifique, cela prend beaucoup de temps (près de 30 secondes) et finit par aboutir à

erreur

	from (discourse):1:in `<main>'

Après quelques expérimentations, il semble que cela soit dû à une référence de téléversement particulière qui est utilisée plusieurs fois (plus de 25) dans le même post :

Screenshot 2025-04-03 at 17.11.56

Le temps nécessaire pour rebaker le post est proportionnel au nombre de fois où cette image est référencée (1 à 2 secondes par utilisation). Si elle est mentionnée suffisamment de fois, elle finit par atteindre l’erreur de délai d’attente. Cependant, si une autre image téléversée est mentionnée autant de fois ou plus, le rebake est toujours instantané.

Sauvegarder la même image et la téléverser à nouveau ne reproduit pas le problème. Le problème semble donc être lié à une référence de téléversement particulière.

Si tout cela n’est pas assez étrange, ça devient encore plus bizarre. Remarquant que l’image re-téléversée incluait l’extension de fichier dans la référence de téléversement, j’ai essayé d’ajouter .gif à la référence de téléversement problématique et… alors le rebake fonctionne instantanément comme il le devrait – même lorsque la même image problématique est utilisée des dizaines de fois. En d’autres termes, j’ai changé quelque chose comme

![foobar|15x15](upload://w5ilVpOCq4ZcvEahAisyiR1pzhu)

en

![foobar|15x15](upload://w5ilVpOCq4ZcvEahAisyiR1pzhu.gif)

et, d’une manière ou d’une autre, cela a fait disparaître cet étrange erreur de délai d’attente.

Hypothèse : un nouveau traitement doit être effectué sur cette image e0ded3304aff1477bae442c0ead0050210dce4f0 et pour une raison quelconque, elle échoue de manière répétée, prolongeant le processus de cuisson suffisamment longtemps pour qu’il échoue finalement ? Je ne suis pas sûr de la suite.

Dans tous les cas, cela semble être un bug qui mériterait une attention particulière – peut-être que les @moderators pourraient le déplacer dans Bug s’ils sont d’accord ?
