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.
