Thrashing - - Thrashing is term referred to a high paging activity. - A process is thrashing if it is spending more of its time paging than actually executing. - Consider a process that currently needs some more frames. Currently all the frames are occupied. So it will have to swap with certain pages; however since all the pages are actively being used, there would be need for an immediate page replacement after this. Such a scenario is called thrashing - It results in serious performance problems.
