Course Introduction:Solution to the Linux zombie process that cannot be killed: 1. Use the cat command to view the parent process ID of the zombie process. The syntax is "cat /proc/zombie process ID/status"; 2. Use the kill command to kill the parent process. Just die, the syntax is "kill -9 process number of the parent process".

Course Introduction:The Linux zombie process is a process that has died long ago, but still occupies a position in the process table; if the parent process does not have wait() when the child process dies, you can usually use ps to see that it is displayed as "

Course Introduction:In Linux systems, zombie processes are special processes that have been terminated but still remain in the system. Although zombie processes do not consume many resources, if there are too many, they may cause system resource exhaustion. This article will introduce how to correctly remove zombie processes to ensure the normal operation of the system. 1Linux zombie process After the child process completes its task, if the parent process does not check the status in time, the child process will become a zombie process. The child process is waiting for confirmation from the parent process, and the system will not recycle it until it is completed. Otherwise, the zombie process will continue to hang in the system. To check whether there are zombie processes in the system, you can run the command top to view all running processes and possible zombie processes. The result of the ‘top’ command can be seen from the figure above in Linux.

Course Introduction:This article mainly introduces Linux zombie processes and methods to clean up zombie processes. 1. What is a zombie process? Zombie processes (Zombieprocesses) in Linux are sometimes called failed or dead processes. They are processes that have completed execution, but their entries have not been removed from the process table. 1.1 Process status Linux maintains a process table, which contains all running processes and their status. The following is a brief introduction to various process states: (1) Running (R): Indicates that these processes are currently running or runnable, represented by the letter R. Note: The process is in R state, which does not mean it is running, but it means it can be scheduled. In other words, a process can only be scheduled if it is in the R state. Other states must be transferred first.

Course Introduction:A Linux zombie process is a process that has terminated but its parent process has not yet processed the aftermath to obtain information about the terminated process; a zombie process is when the child process ends before the parent process, and the parent process does not recycle the child process, release the child process resources occupied, at this time the child process will become a zombie process.
