When you look at the active program in the windows task manager, it shows the DOS window. I have a command prompt open, within that command prompt I have an exe running. Or to reiterate, find out the cause of the problem and fix that.ĬI have a windows machine (win2k) that has what I consider to be a zombie process. Make a report to the maintainers of the package.
#UNIX PROCESSES STATES PATCH#
See if there is a patch that fixes the issue.
So, what to do? find out what is spawning these processes, and why it is not shutting them down when they exit. Having a few zombie processes tying up nearly no resources at all is not a critical state, and using kill -9 is like chasing a mouse with a heavy hammer you’re not likely to get the mouse, but you may do extensive damage to everything around you in the process. That said, you should never, ever be using ‘kill -9’, that is an absolute last-ditch resort for dealing with a system that is almost non-functional or in some other critical state. Removing them is like taking a cold tablet, you are deling with the symptom, not the real problem. You need to find out why you have them in the first place.
The only time you should be concerned is if you have a large number of them and said number is continuing to grow, in which case getting rid of the zombies is not your problem. Zombie processes are dead, they consume nearly zero system resources. Run again?
