Patch level detected:Sysload Agent for Unix
Product Version: Sysload 5.8.0

Description :The calculation of physc per process seems not to be coherent with the total physc used by the LPAR

Cause

Cause type:
By design
Root Cause: This is expected behaviour of the agent for AIX.

Environment

OS: IBM AIX
OS Version: all AIX

Resolution

Sysload stats are coherent with the topas stats, short life processes are not seen either in topas but they contribute to the physc of the system.
