MPW_WAITLIMIT is a dynamic system parameter that sets the number of pages on the modified-page list that causes a process to wait until the next time the modified- page writer writes the modified list. This parameter limits the rate at which any single process can produce modified pages. If this value is less than MPW_HILIMIT, a system deadlock occurs. The value for this parameter is normally equal to MPW_HILIMIT.
MPW_WAITLIMIT has the AUTOGEN and DYNAMIC attributes.
