How to properly kill zombie processes in Linux
Feb 19, 2024 am 10:40 AM
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.

Detailed explanation of Linux process priority adjustment method
Mar 15, 2024 am 08:39 AM
Detailed explanation of the Linux process priority adjustment method. In the Linux system, the priority of a process determines its execution order and resource allocation in the system. Reasonably adjusting the priority of the process can improve the performance and efficiency of the system. This article will introduce in detail how to adjust the priority of the process in Linux and provide specific code examples. 1. Overview of process priority In the Linux system, each process has a priority associated with it. The priority range is generally -20 to 19, where -20 represents the highest priority and 19 represents
Why do processes in Linux sleep?
Mar 20, 2024 pm 02:09 PM
Why do processes in Linux sleep? In the Linux operating system, a process can become dormant due to a number of different reasons and conditions. When a process is in a dormant state, it means that the process is temporarily suspended and cannot continue execution until certain conditions are met before it can be awakened to continue execution. Next, we will introduce in detail several common situations when a process enters hibernation in Linux, and illustrate them with specific code examples. Waiting for I/O to complete: When a process initiates an I/O operation (such as reading
C++ Concurrent Programming: How to avoid thread starvation and priority inversion?
May 06, 2024 pm 05:27 PM
To avoid thread starvation, you can use fair locks to ensure fair allocation of resources, or set thread priorities. To solve priority inversion, you can use priority inheritance, which temporarily increases the priority of the thread holding the resource; or use lock promotion, which increases the priority of the thread that needs the resource.
C++ Concurrent Programming: How to do thread termination and cancellation?
May 06, 2024 pm 02:12 PM
Thread termination and cancellation mechanisms in C++ include: Thread termination: std::thread::join() blocks the current thread until the target thread completes execution; std::thread::detach() detaches the target thread from thread management. Thread cancellation: std::thread::request_termination() requests the target thread to terminate execution; std::thread::get_id() obtains the target thread ID and can be used with std::terminate() to immediately terminate the target thread. In actual combat, request_termination() allows the thread to decide the timing of termination, and join() ensures that on the main line
