Thanks for your advice everyone. Graham: The 250ms interval seems to me to be the crux of the problem. I was hoping for a way to adjust it. We don't have all that many "user work" address spaces started. Usually only one CICS region.
Jim: I've set RMPTTOM to 45000. Going from 3000 to 15000 didn't seem to have an effect, but I was hesitant at shooting too high. Allan: We have little to no usage of those subsystems--even CICS is pretty lightly used. My goal is to reduce the CPU usage in the WLM & other system address spaces because we pay for CPU cycles. Peter: That's correct.
