最初，我尝试通过生成多进程来避免 lxml 内存泄漏并终止它，但失败了。
因此，在尝试新想法之前，我在服务文件中设置OOMPolicy=stop, 。MemoryMax=2G
我的意图是，如果 podman stats 中的内存使用量达到 2G，systemd 的 OOM-killer 会发送 stop（而不是来自内核的 SIGKILL）。所以它将重新启动。
然而，内存使用量podman stats是164.9MB，但systemctl status结果是Memory: 756.0K (high: 1.8G max: 2.0G available: 1.8G)。（你可以忽略高。我刚刚尝试过--runtime。）
当然，实验会显示一些东西，但我想听听关于内存的解释..因为unix会有我还不明白的行为原因。
