When this happens, you need to do a system restart to get a dump, and open a PMR. You don't have to debug it; that's what you pay us for. :-) Looking at your operator's console logs and performance monitor data for hints would be a Good Thing. Make sure you process any EREP records. Alan Altmark z/VM Development IBM Endicott
