VMS Help RUN, Process, Qualifiers, /QUEUE_LIMIT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /QUEUE_LIMIT=quota

    Specifies the maximum number of timer queue entries that the
    created process can have outstanding at any one time. This number
    includes timer requests and scheduled wakeup requests.

    The default quota is the quota established at system generation
    time. A process does not require any timer queue quota in order
    to execute.

    The timer queue entry quota is pooled.
