All of this with 8gig? It's certainly doable but I wouldn't recommend it. Do you have any XSTORE (extended storage) defined? Issue a QUERY XSTORE command if you don't know. I'd say you might have some paging issues. Steve

Your answer makes perfect sense. Yes, I running about 20 zLinux guests and 6 z/OS guests on a z800 with 8Gb real. We're still running the original default values and I've probably grown to the point where I need to be looking at these values closer. I do have sufficient PAGE packs added, but I admit, I don't know much about SRM - so I'll check into it.

Are you running more linux guests than usual? or increased their memory size? did/are other guests going into eligible list too? </snip>
