Kswapd0 is consuming a lot of CPU.
Issue Recently, a Linux server has been experiencing high CPU usage, causing the server to become unresponsive and other processes to fail to execute smoothly. By using the top command to check resource usage, it can be seen that the kswapd0 process is consuming a large amount of CPU resources. Cause and solution Based on my research, the kswapd0 process is responsible for managing virtual memory. Typically, a Linux system comprises RAM, swap, and EXT4 components. The EXT4 partition is used to store regular files and can be created on either an HDD or an SSD, though it is relatively slower compared to RAM. RAM, commonly referred to as memory, is used for high-speed program execution. The swap partition, on the other hand, is used as additional virtual memory and is normally allocated on physical disks, especially on machines with limited physical RAM. ...
