According to the progam check table in my Principles of Operation reference summary, interruption code (= program check code) 0x60004 is a protection exception. The program is writing to memory that is memory mapped as read-only. This is a user program, therefore the next step is to create a core dump and see why it did that. with kind regards Carsten Otte System z firmware development / Boeblingen lab --- Every revolution was first a thought in one man's mind; and when the same thought occurs to another man, it is the key to that era. - Ralph Waldo Emerson, Essays: First Series, 1841 Tom Huegel tehuegel@gmail.c omTo Sent by: Linux on LINUX-390@vm.marist.edu, 390 Port cc linux-...@vm.mar ist.edu Subject ABENDS 04.02.2014 00:07 Please respond to Linux on 390 Port linux-...@vm.mar ist.edu I'm a LINIX dummy.
