Question

Tengo TAKS Capistrano como este

require "bundler/capistrano" 

set :application, "cloudoc" 
set :repository, "git@github.com:luizkowalski/cloudoc.git" 

set :scm, :git 

role :web, "xx.xx.xx.xxx" 
role :app, "xx.xx.xx.xxx" 
role :db, "xx.xx.xx.xxx", :primary => true 

default_run_options[:pty] = true 
ssh_options[:forward_agent] = true 

after "deploy:restart", "deploy:cleanup" 

set :user, "deploy" 
set :use_sudo, true 

set :deploy_to, "/home/deploy" 
set :deploy_via, :remote_cache 

role :web, "xx.xx.xx.xxx" 
role :app, "xx.xx.xx.xxx" 
role :db, "xx.xx.xx.xxx", :primary => true 

después de la cap deploy esta es la salida.
por alguna razón, falla y no sé por qué. Lo he intentado con use_sudo false y con root, sucede lo mismo.

Answer 1

El núcleo mata activamente los procesos de memoria RAM cuando es corto y procesos a utilizar toda la memoria RAM. Puede usar dmesg para ver si el kernel ha matado al proceso. Aparecerán mensajes como este:

[ 3380.091822] Out of memory: Kill process 1075 (ruby1.9.1) score 382 or sacrifice child 

Puede activar el espacio de intercambio o cerrar otros procesos. Si está ejecutando un VPS, asegúrese de tener suficiente memoria RAM disponible. La solución más simple, si los problemas son realmente una escasez de RAM libre, es simplemente comprar más RAM.

Answer 2

Si está utilizando una instancia de amazon EC2 micro intente eliminar las versiones anteriores de su aplicación y luego reinicie la instancia del servidor. Esto funcionó para mí. tapa desplegar: limpieza tapa de caucho: reiniciar

Answer 3

Estoy ejecutando mi aplicación de rieles en Digital Ocean. Crear un intercambio de 2gb parece resolver el problema.

Answer 4

Me encontré con este error y me di cuenta de que estaba almacenando todos mis lanzamientos anteriores. Simplemente utilicé cap deploy:cleanup y funcionó muy bien.
