你好，据我理解您应该是自己创建了test子目录，然后echo一个pid进去的是么？

systemd从235版本开始会在daemon reload跟restart的时候做cgroup的刷新操作，是这个commit引入的： https://github.com/systemd/systemd/commit/58d83430e1276fe8d1224c2b5f76e756d143a375

systemd本身会对服务及其子进程的cgroup进行管理，所以不推荐自己创建cgroup子目录然后echo pid的做法，因为这样的做法systemd感知不到，信息没有被记录到，所以reload之后就被清空了。systemd有官方推荐做法，参考这个issue： https://github.com/systemd/systemd/issues/15496

关于升级251之后问题解决这一点，请问您是如何升级的呢？Anolis本身没有提供更高版本的systemd。
