The freed space may come from programs that are not operating for a long time, and these freed spaces are temporarily saved to the swap space, waiting for those programs to run, and then recover the saved data from swap to memory. In this way, the system always swaps when there is not enough physical memory. In fact,

A summary of memory exhaustion:1) before the process receives an oom, the kernel refreshes the file system's cache to free up space.2) Move the Swap area page to disk.3) When memory becomes small, virtualization enables each process to make a simple context switch through the swap area.4) Out-of-memory (OOM) is raised to kill those processes when the process cons
