</P>
<BR>

<P><FONT SIZE=2>Good day all.</FONT>
</P>

<P><FONT SIZE=2>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.&nbsp; These are fairly rare reboots and usually are not hard 
failures.&nbsp; The symptom is simple, an AP, AW, or WP reboots without warning.&nbsp; 
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.&nbsp; As far as I can remember, this problem has existed since the very first 
'B' box was installed in our plant.&nbsp; Now, with nearly 100 of them in service, we 
see altogether too many of them over a years time.&nbsp; Since we have such a large 
number of 'B' boxes,&nbsp; it appears to Foxboro that we here at PPG are seeing more 
of these faults than the rest of the customer base (thats YOU).&nbsp; But I 
wonder???</FONT></P>

<P><FONT SIZE=2>If you would be so kind, please answer the following questions:</FONT>
</P>

<P><FONT SIZE=2>1.&nbsp; Have you ever experienced this failure?</FONT>
</P>

<P><FONT SIZE=2>If so, please continue:</FONT>
</P>

<P><FONT SIZE=2>2.&nbsp; On average, how many times per year?</FONT>
<BR><FONT SIZE=2>3.&nbsp; How many 'B' boxes do you have in service?</FONT>
<BR><FONT SIZE=2>4.&nbsp; What method have you been using to repair (reboot, replace 
cimms, replace 'B' box, etc.)</FONT>
</P>

<P><FONT SIZE=2>Thanks to all who participate...</FONT>
