[SunHELP] Ecache Error

[Fletcher, Joe]

Replacing the CPU may be of some benefit since some modules are more prone
to the error than others.
However, since the root cause of the fault is a basic design feature of the
UltraSPARCII  ALL modules have the problem. The patches use a cache scrubber
program which has the effect of reducing the likelihood of the problem
occurring.

It comes down to use of parity memory instead of ECC in the cache. Changing
to use ECC means a redesign of the chip. For a permanent fix you would have
to use an UltraIII which does have ECC cache RAM.

Bruce and Michael,

Thanks for the QUICK answer!

(Install newest Patch Cluster)

Another question....

While searching the net for more info, I found a site
that replaced the CPU as a result of this error.

??

Is the truly necessary?

Thanks!
