For example, HP OpenVMS may remove a page that does not need to be written to disk (if it has remained unchanged since it was last read from disk, for example) Page Fault Handling Runqueue Balancing in Multiprocessor Systems 7.5.1. For the reason why, consider the following point.Taking our hypothetical application with the 15000 byte virtual address space, assume that the application's first instruction accesses data stored at address 12374. This does not necessarily mean that the page fault was a privilege violation.

The first two counters track the working sets and the file system cache. http://davegaubatz.com/page-fault/page-fault-in-msvcrt-dll.html In that case the kernel delivers a SIGSEGV signal (segmentation fault) to the process: the execution of the process resumes at the signal handler rather than at the original location, but The dentry Cache 12.2.6. A null pointer is usually represented as a pointer to address 0 in the address space; many operating systems set up the memory management unit to indicate that the page that How To Calculate Page Fault

It can consult the special-purpose registers that provide information about the nature of the fault, and if needed it can also inspect the instruction that the program was executing. How To Reduce Page Faults Windows Once the copy has completed successfully, the OS allows the program thread to continue on.
