Yes, my original post was to see if anyone know of PTFs applicable to such a problem with the combination of hardware/software we are using.

If AR does not respond, look to z/VM.

CICS and TCP/IP also seem to be asleep. I only brought up FAQS to attempt to portray how the system fails to respond.

Are the VSE consoles responding when FAQS is not? How many FAQS users do you have? I have a vague memory (and no books at hand) of a limit to the number of FAQS users you can have.

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.

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.
