Re: 520 (Power5) at V6R1 Goes to Sleep

["Jim Franz" <franz400@xxxxxxxxxxxx>]

have u checked the security audit journal?
does it happen at a particular interval?
if the security journal shows nothing I would turn on a comm trace for all 
ip activity.
I have seen network switch blink on & off, and the ethernet retry "consume" 
the system. local network denial of svc or mal formed packets.
Recent cume & groups?
