Rails Rails 内存泄漏的问题
在 EC2 上面跑一个 Rails 的网站，大概每隔个星期就会出现 cannot allocation memory 的问题，重启一下又好了。这个是不是传说中的内存泄漏？
Google 一下做了这几两个事情，用了 oink 来查找内存变化大的地方，用 request-log-analyzer 来分析日志。不知道各位都是怎么解决的？不能总是重启程序吧？

Now, DHH tells me that he’s got 400 restarts a mother fucking day. That’s 1 restart about ever 4 minutes bitches. These restarts went away after I exposed bugs in the GC and Threads which Mentalguy fixed with fastthread (like a Ninja, Mentalguy is awesome).
If anyone had known Rails was that unstable they would have laughed in his face. Think about it further, this means that the creator of Rails in his flagship products could not keep them running for longer than 4 minutes on average.
Repeat that to yourself. “He couldn’t keep his own servers running for longer than 4 minutes on average.”
#4 楼 @feng041921 还是没找到泄漏的代码？ 如果是 unicorn 的话可以设置 worker 内存的阈值，自动杀掉内存大于一定程度的进程。
