Suspicious Kernel Panic

2007-12-24 23:23:00

Hi all,

One of my DB servers running SunOS 5.8 recently planted for no apparent
reason (no other panics before or since). The logs indicate an EDP error on
CPU9, which I understand may be some sort of ecache parity issue?

Could someone help me interpret these logs entires? Do I need to worry
about that CPU or is it something else entirely?

Paul

log entries as follows:
