Mongoid3/Moped: database=admin command={:ismaster=>1}

Question

我已经把我的Rails应用升级到了3.2.8和Mongoid 3/Moped。在我的开发机器上，当设置为生产时，一切都运行得很好，rails c在我的生产设置上也运行得很好。然而，该应用程序不会启动(部署在passenger上)，似乎只是超时，不会产生任何错误。我将log_level设置为在生产环境中调试，如下所示：

我该如何解决这个问题？(根据记录，我尝试使用的数据库不是admin。)

谢谢,

嗯，看起来乘客实际上是在旧的ruby 1.9.2安装上运行的。将Passenger更新到ruby 1.9.3，重新编译了nginx，然后它又可以正常工作了。
