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?

Viendo este mismo error en nuestra instancia al publicar/editar/aprobar un tema con contenido de Markdown muy específico. Se cargará durante un tiempo y luego lanzará un error interno del servidor.

La imagen muestra un cuadro de diálogo emergente con el mensaje "Error interno del servidor", junto con un botón "Aceptar". (Subtitulado por IA)

Para que conste, también hemos visto informes esporádicos de usuarios con errores similares al editar algunas publicaciones (generalmente bastante largas, aunque no cerca del límite), donde hacer cambios minúsculos en el texto parece superar el error (anecdóticamente: agregar otro punto, reemplazar un guion, etc.). Aún no hemos podido encontrar pasos reproducibles, ya que generalmente me entero solo cuando alguien encontró el “truco mágico” para solucionarlo.

También acabo de notar estas advertencias. Cuando comienzan, pueden tener varias repeticiones en aproximadamente una hora, y luego se detienen. Hasta la próxima vez. Juraría que no las teníamos hasta hace unos días.

¿En qué versión estáis, @icaria36 y @Indra? Nosotros estamos en stable, pero me pregunto si esto también está ocurriendo en tests-passed.

Estamos en 3.5.0.beta3-dev (3f353a726b).

Creo que he encontrado algo relacionado con esto y que podría proporcionar más pistas sobre el origen del problema. Se va a hacer un poco largo, así que tened paciencia.

Hoy me he dado cuenta de que tengo un par de trabajos de sidekiq que fallan y se han estado reintentando durante al menos una semana con el mismo error que en /logs.

En la consola, si intento volver a hornear esa publicación específica, tarda mucho (cerca de 30 segundos) y finalmente termina con

Después de experimentar un poco, parece que se debe a una referencia de carga particular que se utiliza varias veces (más de 25) en la misma publicación:

El tiempo que tarda la publicación en volver a hornearse es proporcional al número de veces que se hace referencia a esa imagen en ella (1-2 segundos por cada uso). Si se menciona suficientes veces, eventualmente se produce el error de tiempo de espera agotado. Sin embargo, si se menciona otra imagen cargada tantas veces o más, el horneado vuelve a ser instantáneo.

Guardar la misma imagen y volver a cargarla no reproduce el problema. Por lo tanto, el problema parece estar con una referencia de carga en particular.

Si todo esto no es lo suficientemente extraño, se vuelve más raro. Notando que la imagen que se volvió a cargar incluía la extensión del archivo en la referencia de carga, intenté añadir .gif a la referencia de carga problemática y… entonces el horneado funciona instantáneamente como debería, incluso cuando la misma imagen problemática se usa docenas de veces. En otras palabras, cambié algo como

y, de alguna manera, eso hizo que este extraño error de tiempo de espera desapareciera.

¿Hipótesis? ¿Se necesita algún reprocesamiento para esta imagen e0ded3304aff1477bae442c0ead0050210dce4f0 y por alguna razón falla repetidamente, extendiendo el proceso de horneado lo suficiente como para que finalmente falle? No estoy seguro de cómo continuar desde aquí.

En cualquier caso, esto parece un error que podría necesitar atención. ¿Quizás los @moderators puedan reubicar esto en Bug si están de acuerdo?
