Library /sys$common/syshlp/pca$help.hlb SET, PAGE_FAULTS, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The SET PAGE_FAULTS command enables the collection of page
    fault data. After you enter the GO command with page fault data
    collection enabled, the Collector records in the performance data
    file every page fault that occurs during program execution. The
    Collector records the program counter value, the faulting virtual
    address, and a CPU time stamp for each page fault. You cannot
    collect stack PC values with page fault data.
