Hello,
We have a Test SAP Appl Srv. It should go in prod soon.
REAL Hardware at moment is 2 IFL, enough RAM. later 6 IFLs, more RAM.
System is up 120day, suddenly cpu-consuming starts 2 days ago. System lags like hell.
I found in the internet things like "USB, WLAN driver problems" and "Blaster Attack".
But in zLinux? never saw it before, in no SAP, Ora, DB2, LAMP, whatever zLinux.

VM4.4:
q share li0120
13:59:26 USER LI0120 : RELATIVE SHARE = 100
13:59:26 MAXIMUM SHARE = NOLIMIT
q quickdsp li0120
13:59:50 USER LI0120 : QUICKDSP = ON
