We have noticed SAMS Vantage started task was using excessive CPU in one the LPARs.
This looks to be a message flood from Automation Script AUDITOCD on MSGE-DD.
If you look at the bottom of the Vantage log you will see page after page of:
OBJCAUDO nbrtape=0 volums=A00011
This is coming from:
OBJCAUDO DFSMShsm AUDIT of OCDS started
OBJCAUDO OCDS-NAME=HSM.OCDS *
Release : 14.0
Component : CA Vantage Storage Resource Manager
Apply PTF's SO11427 and SO13209 to correct the AUDITOCD messages.
