Hi Tom, I've also seen 100% usage on a shared IFL used by an LPAR where the "WAIT COMPLETION" flag was set, i.e. the box called "Do not end the time slice if a partition enters a wait state" was ticked. Kind of defeats the purpose of shared PUs, but something to be aware of nonetheless. Later we turned off the flag and the usage was more evident in SYSVIEW, i.e. not 100% all the time.
