What are zombie and orphan processes?
The Zombie process is a process that has been executed but has not been recycled by the parent process because the parent process does not call wait() to read its state; it does not occupy resources but will occupy process table entries. The Orphan process is that the parent process terminates before the child process, and the child process is taken over by init/systemd; it can run normally until it ends. Both are not dangerous, but it should be noted: too many zombie processes will exhaust the process table and the parent process code needs to be repaired; if the orphan process is out of control, it may waste resources, and monitoring should ensure that it ends correctly.
