¿Qué está causando estos errores en mi aplicación Heroku?

Question

Recibo los siguientes errores cuando un trabajador de Heroku ejecuta un trabajo retrasado y no puedo entender por qué. El primer error parece estar relacionado con el Evernote gem, aunque en realidad no tengo ningún código que lo use todavía en todo el proyecto. Todo lo que tengo es

gem 'evernote', "~> 0.9.0" 

in the gemfile.

El segundo parece relacionado con el complemento Heroku Newrelic, que es un servicio de supervisión de aplicaciones. Pero sí supervisa la aplicación, así que no tengo idea de qué podría estar causando el error.

¿Qué está causando estos errores?

Answer 1

La única vez que tengo el mensaje "proceso de parada con SIGTERM" ha sido cuando he terminado el proceso de forma manual - por ejemplo, cuando estaba corriendo script/servidor y luego presione CTRL-C

Este es un mensaje del sistema operativo que indica que el proceso fue terminado por alguien a propósito. No es una falla interna.

Le sugiero que tenga un chat con la gente heroku sobre si su proceso estaba haciendo algo tonto y lo terminaron.

Answer 2

de ayuda heroku:

R12 - Salida de tiempo de espera

Un proceso fallido para salir dentro de los 10 segundos de ser enviado un SIGTERM lo que indica que se debe parar. El proceso se envía a SIGKILL para forzar una salida.

Ver: https://devcenter.heroku.com/articles/error-codes#r12__exit_timeout

Parece que necesita más rápidamente código.
