我正在运行Passenger，当我重新启动Apache时，我得到一个PassengerWatchdog进程，可以达到100％的CPU。
有什么建议吗？
我使用的是Passenger 4.0.5和Ruby 2.0.0p195的Mac OS X 10.8.4。
使用Mac OS X活动监视器，这是我在采样时得到的：

这是一个已知问题，已经解决。虽然修复程序已经提交，但它尚未作为gem发布。查找下一个版本4.0.6，其中应包含修复程序。
目前，您可能要么降级乘客（我没有指出引入此问题的版本，我的猜测是尝试版本＆lt; = 4.0.4）或者从源代码处工作。
以下是错误跟踪器页面： https://code.google.com/p/phusion-passenger/issues/detail?id=908
我们在FreeBSD（OS X的基础）中遇到了这个问题，希望这也能在那里解决它。

我能够通过降级到4.0.3来完成这项工作，然后在使用killall杀死流氓进程后进行硬停止然后启动Apache。
