Re: Best way to locate and kill a zombie
It is still not a real zombie as it's parent it not yet "1", init - the God mother of all processes.
Now try "ps -ef|grep 2718" and see what process is listed?.
A zombie that is attached to init, cannot be killed. They are ghosts waiting to send their status information to their parents that do not exist. So, a good programmer can write a code that will get the status from the waiting child. Once the status is reported, the child will literally die.
If the zombies are not talking too much of CPU (sometimes users report that the defunct process is consuming too much CPU, by misunderstanding how Glance reports), then I will wait for my next maintenance window.

Re: Best way to locate and kill a zombie
root 2718 1 0 Feb 15 ? 0:00 /opt/perf/bin/perflbd
root 3047 2718 3 Feb 15 ? 0:00
root 2733 2718 0 Feb 15 ? 0:57 /opt/perf/bin/rep_server -t SCOo
root 10180 969 2 09:54:37 ttyvb 0:00 grep 2718
Yes it looks like the parent is "1". it does taking any proccessing, but if I have time I will try and find a script, just in case one pops up in the future that does take up processing time. thanks again....

Re: Best way to locate and kill a zombie
The point is that if the parent is not init (PID 1), the "zombie" can be killed by killing off the parent (in your case 2718). I'm not sure what perfldb is and therefore, I'm not sure this is something you want to do, but it's something to remember for next time.

Re: Best way to locate and kill a zombie
This may probably make it a real zombie. If you are lucky, then it may kill it too.
