No, that is not the problem. This is a VERY low-usage system. Even when it seems to be asleep, its CPU usage is less than 2% (from both the VM and VSE perspectives).

Are there any partitions with a high priority than FAQS (that could be dominating the CPU)? Frank M. Ramaekers Jr. ________________________________ From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Wakser, David Sent: Tuesday, December 21, 2010 8:54 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Strange response time problems (also posted on VSE-L) All: We are running 2 2.3 VSE systems under z/VM 5.4 on a Z800 CPU. We are experiencing periods of time when VSEs do not respond at all (e.g. cannot get in via FAQS from CMS, etc.), even though nothing is running in the VSE system and the z/VM system is not very busy. At other times, we have excellent response times, though conditions on either the guests or the z/VM host didn't seem to change. We do not have any z/VM monitors (except Explore, which is not set up properly), and we have even tried QUICKDSP, without success. Is anyone aware of any PTFs that address this strange behavior? We believe it started when the system was upgraded to z/VM 5.4.
