Thrashing is a high paging activity. A process is thrashing if it is spending more time with paging rather than execution.
Thrashing is caused by under allocation of the minimum number of pages required by a process, forcing it to continuously page fault. The system can detect thrashing by evaluating the level of CPU utilization as compared to the level of multiprogramming.
Caused by:-
- Global replacement algorithm.
- Under allocation of the minimum number of pages required by a process.
- Very high degree of multiprogramming.
Eliminated by:-
- Reducing level or degree of multiprogramming.
- Use local replacement algorithm.
- While allocating check minimum sufficient frame required for a process.

How does system detect thrashing?
if your computer has a slow disk drive and you are doing a lot of paging (using virtual memory) to switch from one program to another rapidly, then your disk drive will become a performance bottleneck and your computer will seem to have trouble keeping up with your commands. The computer, here, is "thrashing", spending all of it's time trying to keep up. Imagine a person drowning. They are thrashing because they are spending all of their energy doing one thing to stay alive.
