Hi,
I received few answers to this question. Fortunately the event has
stopped occurring since then. Thank you all for your responses.
Best,

SUMMARY
-------
- From: Olle Eriksson <olle_at_cb.uu.se>
Correctable memory errors. As long as they are not too many they
cause no problems.
- From: Jan Hansen <dkJanHan_at_europe.lego.com>
I have 10 AS500/500MHz with 1Gb of memory and almost all of them has
this error. The system is able to correct single-bit errors.
According to Digital it is acceptable to have x numbers of these per
month per Mb. ??? If the error occur at the same address every time
you should replace the module.
- From: "Huehls, Mark R." <huehlsm_at_indy.navy.mil>
run uerf as root. if you look it up in the man pages you can look at
just memory.
Original Posting:
------------------
Our ALPHASTATION 500/333Mhz came from the factory with 128Mb of
memory. We have then added 256Mb for a total of ~384Mb.
It has been working with no problem for about 4 months. For the past
few days I have been getting the attached error message.
Has anyone seen something like this before? I think this is just a
mismatch of the cache registers and the hardware. But is it a problem
with the caching or the board?
With a simple calculation of the EI address, it appears to be on the
226th Mb (maped on the 3rd party added boards).
Any clues or information will be appreciated. I will summarize.
Thank you.
