谁动了我的内存

[复制链接]
发表于 2008-3-11 13:12:01 | 显示全部楼层 |阅读模式
说见鬼了一点都不过分：）
和往常一下，我放下手边的工作，跑去楼下吃饭。上来以后发现内存被占用了很多，习惯性的将firefox关掉，没什么效果，从top上查看，没有特别惹人注意的地方，觉得很奇怪，准备细查下去。
我把xserver关掉，default服务全部关掉。出人意料，还有400多M的占用。接着我把boot服务都关了(udev没关), 汗到底谁动了我的内存？

从syslog里查看发现
firefox-bin[30511]: segfault at 0000009c eip b6f05058 esp bfb27b50 error 4
这个是在我看一个flash的时候,syslog记录下的，并且当时firefox并没有关闭，也没有出现异常，除了这个，我实在找不到其他可疑的地方了。把swap关掉，把buffer和cache清掉还有402M的占用……我从来没有遇到过这样的情况，也不知道以后是否能重现 =.=|||

重启以后，系统自动把所有服务打开，占用内存:30M，一切正常
以下是我重启前的状态:

  5. -/+ buffers/cache:        402        608
  6. Swap:            0          0          0
