Hello Managers -
Just when you think all of your problems are solved.....
We have noticed an occasional occurrence of a CPU Exception
error event that does not result in a system crash. The system
we are running had the same problem earlier, but it did result
in crashes. We thought the problem had been resolved, but
maybe not.
Our problem before was related to the B-Cache simms, and this may
be as well.
On Feb. 23 we had several of these errors occur (20 of them) in
a time frame of 6 hours. This caught our attention. Now we have
the time to look into the matter.
I am looking for any information regarding these errors. The
following is the only information I have regarding the errors, and
the messages are repeated for each occurrence of the problem.
