The PMDF KILL utility prompts you for each PMDF process and asks
    if you want to kill it.

    The PMDF KILL utility immediately and indiscriminately kills the
    specified process (using STOP/ID), even if that process is in
    the middle of transferring e-mail. So use of the PMDF SHUTDOWN
    utility, which performs an orderly shutdown, is generally
    preferable.
