Bo,
Also, Art Arruda told us at a User's Group meeting that the 51B boxes can experience
panic asynchronous memory faults due to the type of memory that is used. These boxes
do not have ECC memory and will reboot if an error occurs. If this happens, you can
try re-seating the memory chips, as this is a common problem. Sun Microsystems has
stated that you can expect to see at least one of these types of errors every two
years according to Art.

Good day all.
I am trying to gather as much information as I can to help analyze persistent
Asynchronous Memory Error reboots on some, if not all, of our AP51B and WP51B boxes.
These are fairly rare reboots and usually are not hard failures. The symptom is
simple, an AP, AW, or WP reboots without warning. the /var/adm/messages file contains
a message that states a Panic dump was made, the Asynchronous Memory Error was the
reason and also lists the offending memory address. As far as I can remember, this
problem has existed since the very first 'B' box was installed in our plant. Now,
with nearly 100 of them in service, we see altogether too many of them over a years
time. Since we have such a large number of 'B' boxes, it appears to Foxboro that we
here at PPG are seeing more of these faults than the rest of the customer base (thats
YOU). But I wonder???
If you would be so kind, please answer the following questions:
1. Have you ever experienced this failure?
If so, please continue:
2. On average, how many times per year?
3. How many 'B' boxes do you have in service?
4. What method have you been using to repair (reboot, replace cimms, replace 'B' box,
etc.)
Thanks to all who participate...
Bo
