生产资产：Capistrano的过程中预编译失败部署

Question

部署过程中，我得到以下的输出：

[xx.xxx.xxx.xx] executing command 
** [out :: xx.xxx.xxx.xx] ** Invoke assets:precompile (first_time) 
** [out :: xx.xxx.xxx.xx] ** Execute assets:precompile 
** [out :: xx.xxx.xxx.xx] 
** [out :: xx.xxx.xxx.xx] ** Invoke assets:precompile:all (first_time) 
** [out :: xx.xxx.xxx.xx] ** Execute assets:precompile:all 
** [out :: xx.xxx.xxx.xx] ** Invoke assets:precompile:primary (first_time) 
** [out :: xx.xxx.xxx.xx] ** Invoke assets:environment (first_time) 
** [out :: xx.xxx.xxx.xx] ** Execute assets:environment 
** [out :: xx.xxx.xxx.xx] ** Invoke environment (first_time) 
** [out :: xx.xxx.xxx.xx] ** Execute environment 
** [out :: xx.xxx.xxx.xx] ** Invoke tmp:cache:clear (first_time) 
** [out :: xx.xxx.xxx.xx] ** Execute tmp:cache:clear 
** [out :: xx.xxx.xxx.xx] ** Execute assets:precompile:primary 
** [out :: xx.xxx.xxx.xx] Killed 

bundle -v输出1.1.5

我已经找到了解决办法是重新启动服务器和部署之后立马。否则，我无法部署到生产环境，我不知道如何调试此问题，因为除了部署之外，没有任何输出。

编辑：服务器正在运行Ubuntu 12.04 64
