最近重新启动后，服务 systemd 表现得很奇怪。它占用了 60%-100% 的 CPU，这对我来说不会造成太大问题，但它肯定会加热我担心的处理器。
它在/usr/lib/systemd/systemd --system --deserialize 28. 早些时候，它在 2-3 次优雅重启后/usr/lib/systemd/systemd --system --deserialize 21运行。28
这些是日志：

我不确定它是否保密，所以编造了X
这是某种循环systemd。我尝试重新启动几次，但没有运气。我已经向许多管理员展示了它，但他们也无法弄清楚。谁能指出我正确的方向？（因为我不想重新安装操作系统）
提前致谢！！！
