程序因 /etc/localtime 超时而挂起

在我的服务器上，突然大多数程序停止工作（它们只是挂起）。例如午夜指挥官。当我用 strace 调试 mc 时，我看到它挂起stat("/etc/localtime")

当我尝试cat /etc/localtime它时，它无限期地挂起。有人可以帮忙吗？

以下是输出strace cat /etc/localtime

这看起来像是内存或磁盘损坏。检查您的系统日志（例如/var/log/kern.log）以查看是否提到任何磁盘损坏。

无论您是否看到磁盘损坏的迹象，都请运行内存检查。内存测试86+包含在许多诊断套件中，或者您可以下载可启动映像;它也默认安装在 Ubuntu 上（从启动菜单中选择它）。让它运行至少一次完整的运行——您可以将其放置过夜。如果发现错误，请立即更换损坏的 RAM 模块。
