我的系统出现了一些奇怪的问题。如果我做了一些电脑不喜欢的事情，它就会记录 900 000 行错误日志并停止工作。上次发生这种情况时，我刚刚开始玩 DotA 游戏，一切都停止了。检查日志后，我发现了以下内容：

有谁知道如何解决这一问题？
谢谢。

再加上这两者之间的一些其他错误。
答案1
我的 12.04 上的默认日志系统是 rsyslog。它支持删除重复项的选项。这可能有助于减少音量。
https://unix.stackexchange.com/questions/26337/suppress-duplicate-messages-in-rsyslog
在日志率过高的系统上，我们安装了一个名为 logrotate 的工具。 https://www.tecmint.com/install-logrotate-to-manage-log-rotation-in-linux/ 您可以按日期/时间和大小配置轮换率。它还会压缩或删除较旧的日志以节省空间。这可能是另一种解决方法。
最终，生成日志消息的应用程序需要修复。
答案2
问题原来是硬件问题。我的 wifi 适配器不知为何坏了，我换了它之后，问题就解决了。Ubuntu 显然不能处理硬件故障，否则会丢失它。
