[求助]firefox经常打开新标签页后风扇疯转

ccdouble · 2014-09-05 22:39:13

最初的现象是风扇每隔十几分钟就疯转一段时间、机器烫手，top观察发现是systemd-coredump把CPU几乎占满了。
journalctl显示崩溃程序为[Browser]：

systemd-coredump[1151]: Process 1110 (Browser) of user 1000 dumped core.

用网上搜到的方法暂时关闭systemd-coredump后，依然会有这样的情况风扇疯转的情况出现。

再次用top查看发现Browser把一个线程给跑满了

whatis之类的程序查不到Browser。打算用top观察到PID后迅速执行PS查看完整指令，几次尝试之后看到了完整的执行指令：

/usr/lib/firefox/plugin-container -greomni /usr/lib/firefox/omni.ja -appomni /usr/lib/firefox/browser/omni.ja -appdir /usr/lib/firefox/browser 1233 tab

journalctl显示经常Browser崩溃：

kernel: Browser[1252]: segfault at 0 ip 00007fe0fc4ea517 sp 00007fff92595840 error 6 in libxul.so[7fe0fa607000+36bd000]

libxul.so的errno 6没查到是什么错误，原来之前systemd-coredump也都是耗在了这儿

于是我把问题定在了火狐身上。

gdb运行火狐显示的信息：

这个时候gdb退出火狐依然正在运行完全没有被影响，而且这时候只是运行起火狐，我还没有在火狐上进行任何操作。
或者是我gdb用错了？

接下来我不知道要怎么继续了。各位有什么建议吗？

桌面运行的是cinnamon。
firefox附加组件显示有三个扩展：网页版微信、DownThemAll、AutoProxy，六个插件：Divx Web Player、Java Plug-in、QuickTime Plug-in、Shockwave flash、VLC Multimedia plugin、Windows media player plugin。

systemd-coredump gdb 来使用 gdb 检查 core 文件（注意：会比较耗 CPU）。

systemd-coredump 最大的问题就是极其耗 CPU，其次是占磁盘空间。以前我禁用过它，现在不知道怎么禁用了。

百合仙子说：

systemd-coredump 最大的问题就是极其耗 CPU，其次是占磁盘空间。以前我禁用过它，现在不知道怎么禁用了。

我是把/lib/sysctl.d/50-coredump.conf当中的东西都给注释掉了。
因为昨晚我把systemd-coredump给禁了，所以最近的Browser的coredump文件只有昨晚的了

在 gdb 提示符里敲 bt 看看调用栈吧。好像只是插件进程崩溃了呢。

火狐或者编译器的 bug。要处理这种情况，下一步是编译带调试符号的版本然后再看是崩在哪里了，然后去报告。

你可以试试降级到前一个版本。或者下载官网上提供的预编译版本试试。

ccdouble · 2014-09-06 22:58:09

这个是官网上下载的预编译版本，暂时没有那样的现象出现。
