Page Fault Handling conditions like, where the copy on write bit of a page is set and that page is send by more than one process, the Kernel assign new page and copies the content to the new page and the other processes have their instances to the old page. After recopying the Kernel updates the page table load with the new page number. Then Kernel removes the reference count of the old pfdata table store. Where the copy on write bit is set and no programs are sharing the page, the Kernel accepts the physical page to be reused by the processes. It shows the copy on disassociates bit and write the page from its disk copy, because other process can share the disk copy. Then it replaces the pfdata table entry from the page-queue as the new copy of the virtual page is not on the swap machine. It decrements the swap-use count for the page and if number drops to 0, frees the swap space.
