Hello,
I've found lots of entries in the archives, this seems like a common
problem, but not much in the way of summaries.
I have a 4100 (2-CPU's 1GB Memory), running Tru64 V5.1 PK3. A few weeks
after the upgrade to 5.1, several days after updating to PK3, I started
getting "panic (cpu 0): kernel memory fault" at random intervals. The
machine won't stays up for more than a day, usually failing within a few
hours. We replaced the memory, but the same errors continue with no change.
Prior to the upgrade we added couple new cards, a second DEGPA Gigabit
Ethernet card, and a Memory Channel card, but I don't see how they could
possibly be related to these errors.
To make the problem even more confusing, we have an identical 4100
(2-CPU's 1GB Memory), running Tru64 V5.1 PK3 and it works just fine! The
ONLY difference between these two machines is, the failing one has 466MHz
CPU's and the other has 600MHz CPU's, all other cards and adapters are the
same.
It's getting a little frustrating, can anybody help? Here's the
information from "dia".

It look as though we still have a memory problem, but with brand new
memory...? Maybe it's something else that just looks like a memory problem,
but really isn't?
Any help would be appreciated.
Thanks,

UNIX is very user friendly, It's just very particular about who it makes
friends with.
