Hi list, Last few days we have a strange problem VTAM CPU usage is increased by 50% and we can't determine the cause ... When we analyzed the VTAM CPU utilization using Omegamon we saw that a module: ISTLUCRT is the main module causing the high CPU usage. We couldn't find almost any information regarding this module and it's functions... Thanks for any information or any other ideas... (ZOS 1.4) Dana.
