ZOMBIE: Zombie State, a state that represents the end of a process but not yet extinct, when the process has finished running and freed most of the resources, but the Process Control block has not been released .
The process state that corresponds to the zombie is also running (running or waiting), uninterruptable (non-interruptible blocking state), interruptable (interruptible blocking state), STOPPED (pending state).
Workaround:
#ps-A-o stat,ppid,pid,cmd |grep-e "^[zz]"//View specific process: #kill-9 PID number//Kill Z Process (these actions are more dangerous, I hope in the real server above the cautious use!!!) )
If the z-process is more, the following is the participation of online
#ps-A-O stat,ppid,pid,cmd | Grep-e ' ^[zz] ' | awk ' {print $} ' | Xargs kill-9
