- I'm learning to manage a Wyse 9000i running Wyse's Sys V Unix, and have
- a question concerning zombie processes. A few days ago, the current
- admin rebooted the machine to clear out some processes he described as
- "defunct". I asked how you see these processes, and he said to use ps.
-
- So I did. And I read up in the man pages about ps. The process state 'Z'
- means the process is in zombie state, and that it is finished but the
- parent process has not begun waiting for it. If it does in fact even
- HAVE a parent process, the process is marked as <defunct> in the
- listing. So I'm thinking, the mere fact the process is marked defunct
- means it has a parent that very well may come a' lookin' for the zombie.
- Am I right?
-
- Are zombie processes really a problem, and if so, can't the kill command
- be used to get rid of them? I hate the idea of rebooting the machine all
- the time and don't think it is needed.
