Question

我正在研究Rails应用程序，此时似乎已经杀了我的iMac上的内存，直到我最终必须重新启动。我在OSX 10.6上有一个2.66 GHZ处理器和4GB Ram。

当我启动rails应用程序时，内存消耗显示如下（ps aux | grep rails）：

Gavin      726   0.0  3.8  2590812 158860 s000  S+    9:27am 0:09.90  /Users/Gavin/.rvm/rubies/ree-1.8.7-2011.01/bin/ruby script/rails s

RSS低至158,860 kb 在向localhost发出一些请求后，这个号码会跳到：

Gavin      726   0.0 14.1  3031792 592888 s000  S+    9:27am 0:27.00  /Users/Gavin/.rvm/rubies/ree-1.8.7-2011.01/bin/ruby script/rails s

592,888 kb !!

随着一般开发的使用，它一次又一次地上升再次：

Gavin      726   1.5 25.0  3487516 1050180 s000  S+    9:27am 0:59.29 /Users/Gavin/.rvm/rubies/ree-1.8.7-2011.01/bin/ruby script/rails s

我正在使用RVM运行REE ruby 1.8.7（2010-12-23 patchlevel 330）[i686-darwin10.6.0]，MBARI 0x6770，Ruby Enterprise Edition 2011.01

该应用正在使用Rails 3.0.6

应用程序不是特别密集SQL，而且差不多加载记录时不包含任何关联（不需要建筑）。

我是否正确地说这是内存泄漏或者还有别的东西我应该看看？

有人可以就如何解决这个问题提出一些建议吗？

谢谢！

Answer 1

看起来你有一些内存泄漏。尝试使用内存分析器：https://github.com/ice799/memprof

Answer 2

aasm在cache_classes = false（这是开发模式中的默认值）时非常快速地泄漏内存。你确实使用了很多宝石，但我愿意打赌aasm支持这一点。

正如其他人所说，最好使用内存分析器。

Answer 3

检查config / newrelic.yml：

developer_mode: false|true

如果设置为“true”，那么内存问题可能就是这个。

有人可以告诉我Rails内存消耗吗？
