Resoultion:

The CPU most likely needs to be replaced.  I'll be re-seating the cpu and memory modules then cleaning with some compressed air.  If that doesn't work I'll replace the CPU.  


Original Question:

Hello,

I've been having a problem for about 6 months now regarding one of my Ultra 10 systems panicing.  It appears that the issue is related to a memory error.  I have tried the following:

1) Removed one piece of Memory at a time as to try to isolate the isssue as bad memory, no help.  Behavior is exhibited irregardless of memory module or location of Memory.

2) Patched Operating environment (Solaris 9, latest as of Jan 4, 04)

3) Flashed OBP / Firmware

This system is out of warranty, and my only other thought would be that it is a bad processor.  Does the following output from /var/adm/messages agree with that theory?
