The percentage of slots in use on a local page data set exceeds the current Warning threshold. When usage approaches 30%, paging efficiency begins to decline, and blocked paging disappears at about 35% occupancy. Once this situation occurs, prepare to PAGEADD another data set if the Critical threshold is passed. If the current PAGTOTL setting in IEASYSxx does not allow another data set to be added, it should be increased before the next IPL.
