syslog和文件kern.log不断地填满我的系统，而且似乎网络（wifi 停止工作、无法连接到 VPN 等）停止工作。读取日志似乎是一些网络问题。问题是，当这些日志文件开始填满时，它们也会停止工作。sudo如果我输入任何命令，sudo它甚至不会要求输入密码，只是挂断电话。要获取日志条目，我必须使用su -。重新启动并删除日志文件后，一切都恢复正常——wifi 开始工作，sudo也开始工作，能够连接到 VPN。目前，我好像每半小时就必须重新启动并删除日志，这真的很令人沮丧。我尝试在谷歌上搜索解决方案，但没有找到与我相关的案例。
以下是我能保存的日志，这些日志syslog不断重复并占用磁盘空间（相同的日志kern.log）：
