听起来你的SSH连接出了问题。你能够通过SSH登录到这个服务器吗？ - CDub

Answer 1

Rails 4.1无法通过Capistrano 3部署

看起来服务器的内存不足。我刚把我的RAM从512MB增加到1GB，就解决了这个137错误。

Answer 2

我同意@iamthing的答案。当我试图在Digital Ocean上部署我的小站点时，我遇到了同样的问题。为了跳过这个错误，我按照以下步骤进行操作。

1.安装htop CPU监控软件以检查CPU使用情况。

sudo apt-get install htop

2.通过以下方式停止独角兽web服务器进程

 ps aux | grep 'unicorn' | awk '{print $2}' | xargs sudo kill -9

3. 运行 htop 监控 CPU 使用率

4. 再次尝试部署
