/sys$common/syshlp/helplib.hlb RUN, Process, Qualifiers, /SERVICE_FAILURE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /SERVICE_FAILURE
       /NOSERVICE_FAILURE (default)

    Enables or disables an exception condition notification if an
    error occurs during a system service request. By default, an
    error status code is returned to the process.

    If you specify the /SERVICE_FAILURE qualifier and an error
    occurs during a system service request, the process encounters
    an exception condition.
