There are still many differences between the Linux system and the Windows system in terms of operation. Some friends who have just started using the Linux system often do not know how to operate it. Today, the old boy education editor will explain to you the common CPU problems of the Linux system. And its solution, the following is the detailed content:
1. Frequent CPU overload
CPU overload is a common problem, especially with servers running heavily loaded applications. If the CPU is seriously overloaded, the system's response speed will slow down or even crash. To solve this problem, follow the steps below:
1) Use the top command to view the current CPU usage.
2) Use the ps command to see which processes use a lot of CPU resources.
3) Use the kill command to kill the process that occupies too much CPU resources. If the problem still exists after killing the process, you can optimize the system, increase the CPU or adjust the settings of the application.
2. Frequent CPU crashes
CPU flashback refers to the phenomenon that the system suddenly shuts down or restarts during operation. This problem is usually caused by a hardware failure or a system error. If you are experiencing this problem, you can try the following solutions:
1) Use the system monitor tool to check the temperature and voltage of the CPU. If the CPU temperature is too high or the voltage is unstable, it is recommended to replace or repair the hardware.
2) Check the system log for other error messages. If so, try repairing or reinstalling the operating system.
3) Check for faulty drivers or software. If yes, update or reinstall those drivers or software.
3. Frequent CPU freeze
CPU stuttering refers to the phenomenon that the system becomes slow and unstable during operation. This problem is usually caused by the gradual depletion of CPU resources due to long-running. Here are some workarounds:
1) Before running a large application, use the top command to view the current CPU usage. If the CPU resource is close to the limit, it is recommended to wait for other tasks to complete or increase the CPU resource.
2) Check for unnecessary processes or services running in the system. If there are, try stopping those processes or services.
3) When running large-scale applications, use multi-threading as much as possible to spread the load of CPU resources. This can improve system performance and reduce CPU stuttering.
