How do I to avoid zombie process in Linux?
Editor’s Note: A zombie process is an application or service that sucks up a great deal of system resources, without actually doing anything.
you can’t kill the zombie process with SIGKILL signal as you kill a normall process, As the zombie process can’t recive any signal. so having a good habit is very important. the child process will send SIGCHLD signals to the parent process when its dies. by default, this signal is ignored by system, so the best way is that we can call wait() in the signal processing function, which could avoid the zombie stick around in the system.
You have to see which program created the Zombie perhaps the uninstall did not went well so reinstall and uninstall?
