A process can leave its process group but can never (at least not without root privilege) leave its cgroup. Not the answer you're looking for? This entry is still needed to allow the process that started the (now zombie) process to read its exit status. Obviously this has the problem that, some random process may be stopped for some milliseconds.

  2. I also gave a shell script example because it explained the problem.
  3. First of all a Zombie process is not an orphan process.
  4. Anyway did you try to send a signal to the parent letting it know that its child is a zombie (Something no parent is ready for).
  5. It should be attached.
  6. I walked by the aforementioned computer and all the "cameras" had gone white.
  7. Now, the app doesn't exist in the Task Manager, so I tried to find its PID and kill it, which led to this interesting result: C:\Users\username>netstat -o -n -a | findstr
  8. If you can't guarantee that the work queue manager won't also be killed without warning, then option 2 is your only choice I think, since the only thing you know for
  9. If yes than you can kill it from there, but only after you investigate what it actually is (you can see all the dlls loaded into the process) share|improve this answer

killing the parent has turned that process into a zombie, and the grandparent has read the parent's exit code, so the parent is truly gone).

Hacking longrunningthing to drop dead by itself, or keep/remove its PID on the FS would do but I'm thinking of the generic situation here.

The parent process is responsible for picking up the exit code of the process; the process remains a zombie until this is done. So, immediately after launching your process, do md5sum /proc/[pid]/maps and save the result. Uninstall anything from WISE. If you do have one, try disabling it and then launching your program and closing it and seeing what happens.

When a process loses its parent, init becomes its new parent. It would be interesting to see if VLC solves the freeze that you mentioned: "ReloadEvery" to refresh the page every 5 minutes so the stream doesn't freeze up. EDIT 2: Quoting from Wikipedia On Unix and Unix-like computer operating systems, a zombie process or defunct process is a process that has completed execution but still has an entry in The file descriptor can be passed to setns(2). You can isolate a group of processes - basically any number of processes - by namespacing their init.

timeout will also take extra care to report the correct exit status, handle other corner cases (like SIGALRM blocked/ignored on startup, handle other signals...) better than you'd probably manage to do The basic approach here is that you can create a new PID namespace by using the CLONE_NEWPID flag with the clone system call (or via the unshare command).
