Finally we replaced the memory module with problems and the problem
disapeared, no more cpu exceptions.
Below some of answers to my questions:

It shows as a correctable error, likely a single bit error.
uerf lies about it being severe priority, it isn't.... Digital likely
isn't going to fix that lie in uerf since they're moving to dia.
These can be fairly common with 2100's, the correctable errors which
only become an issue if they start becoming frequent in which case
you'd want to schedule a preventative replacement.
As you've extracted above it is memory module 0.

>will apreciated,
I'd suggest you just keep an eye on it for frequency and not worry about
low volumes. If you are concerned about the volumes and have a service
contract, contatc Digital.
Scripts to extract the information from uerf|dia in a human readable form
vs. the dia|uerf jumble can be found referencing ua_uerf with the kit:

I think this is a know bug at Digital on uerf
uerf claim CPUEXCEPTION but it's NOT, it' a memory error.

Hello,
We had similar "CPU Exception errors", first of all we replaced the CPU
board
and then we replaced a bad memory simm and the latter seemed to fix the
problems
Hope this helps.
