Thrashing or drive or disk thrashing occurs when the hard drive is stressed with transferring information between the system memory and virtual machine excessively. In thrashing, there is a large number of processes running in the system and the system memory is too small to handle all processes. Thrashing leads to decreased system performance and hard disk failure.
To stop the impact of thrashing, install more RAM, end unimportant progam processes etc.
