What to do if the Linux zombie process cannot be killed
Article 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".

What is a linux zombie process?
Article 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 "<defunct>", so Zombie processes are generated; if a large number of zombie processes are generated, the system will not be able to generate new processes because there are no available process numbers, so zombie processes should be avoided.

How to properly kill zombie processes in Linux
Article 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.

How to kill zombie processes in Linux
Article 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.

What does linux zombie process mean?
Article 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.

No more fear of process deadlock - solution to Linux process freezing
Article Introduction:When using Linux systems for development or operation and maintenance, we often encounter process deadlock problems. When a process deadlocks, the response speed of the entire system will be significantly reduced, or even cause the system to crash. However, as a Linux enthusiast, we no longer have to be afraid of process deadlock. Because the Linux system provides a powerful tool - process freezing, which can effectively solve the process deadlock problem. This article will introduce in detail the principle and application method of Linux process freezing. 1. What is process freezing? Process freezing technology (freezingoftasks) refers to placing user processes and some kernel threads in a "controllable" suspended state when the system hibernates or suspends. 2 Why freezing is needed

How to use the kill process command in Linux
Article Introduction:In Linux, the kill command is used to kill processes in the system. The steps are: 1. Use ps, top, pgrep and other commands to obtain the process number of the specified application; 2. Use the kill command to kill the process based on the process number. Syntax "kill -15 process_id" or "kill -9 process_id". Execution principle: The kill command will send a signal (mostly a termination signal) and the PID number of the target process to the operating system kernel, and then the system kernel will perform corresponding operations on the specified process based on the type of signal received.

There are several states of linux processes
Article Introduction:The Linux process has 6 states: 1. R executable state, only processes in this state can run on the CPU; 2. S interruptible sleep state, the process in this state is suspended because it is waiting for a certain event to occur. Suspend; 3. D uninterruptible sleep state, the process is in sleep state, but the process is uninterruptible at this moment; 4. T pause state or tracking state, send a SIGSTOP signal to the process, and it will enter in response to the signal T state; 5. Z zombie state, indicating that a process is about to die; 6. X death state.

How to execute zombie and orphan processes in a single C program?
Article Introduction:In this section, we will see how to execute zombie and orphan processes in a single program in C/C++. Before getting to the point, let's first understand what zombie processes and orphan processes are. Zombie Process A zombie process is a process that has completed execution but still has remaining space. Entry in the process table. Zombie processes usually occur in child processes because the parent process still needs to read the exit status of its child process. Once this is done using the wait system call, the zombie process is eliminated from the process table. This is called harvesting zombie processes. Orphaned Processes Orphaned processes are those processes that are still running even though their parent process has terminated or completed. A process may become orphaned intentionally or unintentionally. Intentionally orphaned processes run in the background without any manual support. this

In-depth exploration of process analysis technology under Linux!
Article Introduction:As a Linux system developer, have you ever encountered problems such as process freezes and application unresponsiveness, but you don’t know how to effectively analyze and handle them? If that's the case, then you've come to the right place! This article will introduce process analysis technology under Linux to help you gain a deeper understanding of the mechanism of process operation and effectively discover and solve problems. 1. What is ps? To monitor and control a process, you must first understand the situation of the current process, that is, you need to view the current process. The ps command is the most basic process viewing command. Use this command to determine which processes are running and their running status, whether the process has ended, whether there are zombies in the process, which processes occupy too many resources, etc. In short, most of the information
