It looks like you have a bad memory module or CPU, assuming you have a service contract with sun, you need to get them to check the explorer output and change the hardware

Thanx liddler,
how can i know the error is due to bad memory or cpu.how to read the error.

I don't know, any error like this I pass to Sun, as they support the hardware on all of my systems.

You could have a look at the output of
/usr/platform/`uname -i`/sbin/prtdiag -v
to see  if that reports any hardware problems

Also have a look at:

liddler is correct. It's an E-Cache ("E$") error, which means that there is some kind of hardware problem with the CPU cache memory.

If you send that data to Sun, they will most likely accept it as proof of a hardware failure and fix it for you if you have a support contract or are covered under warranty.

Its sure that its E-cache problem.

This following link will help you to understand conversion as well.


you may need to replace CPU on board 0

Just one point to clarify regarding Sun's support policy on the E-cache errors having spent the last 6 years in a Sun Solution Centre (before I was laid off and my job got out-sourced to low-cost engineers in India):
If this error has just been a one-off event then Sun Support is likely to say "call us next time it happens again on that CPU *then* we'll replace it."

If this has happened more than once already then Sun should replace the CPU module.

Believe it or not, transient e-cache errors can be caused by cosmic rays, however the chances of naturally occurring causes of the error hitting the same CPU twice are almost zero. Hence the "replace after 2 hits" policy.

The newer UltraSPARC III CPUs now in all new Sun h/w have ECC functions to allow single bit error correction on transient e-cache errors and the latest policy on replacing those CPUs is >24 errors in 24 hours, or immediately on any double bit errors.

A very detailed scientific document on the subject of naturally occurring causes of memory faults can be found at the following URL:

Don't ask me how I came to have this URL, I bookmarked it years ago and it's thankfully still there, otherwise people wouldn't believe me when I mention cosmic rays.  HTH

Hey liddler: what about some points for the info about cosmic rays?  :-)
