A process is classified by the kernel as a zombie if its termination has not been acknowledged by its parent process.
A high number of zombie processes indicates that one or more processes are not handling their child processes properly. You may need to kill the parent process to eliminate its zombie child process.

For each process, you can view the information that follows:
|PID||The process identifier for the specified process.|
|PPID||The process identifier for the process that is the parent of the specified process.|
|UID||The user identifier for the user to whom the process belongs.|
|State||Z for Zombie. That is, the process has been terminated and the parent process is no longer waiting.|
|Priority||The basic priority assigned to the process – the lower the number, the higher the priority.|
|Nice||The Nice value describes the relative priority of the specified process. A process with a low Nice value is running at a higher priority than a process with a high Nice value.|
|CPU Utilization||A value representing the amount of CPU time used by the process. The metric used here may differ across Unix implementations.|
|Terminal||The Unix terminal session where a user started the specified process. If the process was not started by an interactive user, the Terminal value is set to "?".|
|Command||The command executed by the process.|
