Dear Kevin
The whole string is "panic[cpu0]/thread=3D0x609c65a0:trap" in the
/var/adm/messages file.
The vmstat 10 10 gives me around 88% idle time on nearly all attempts.
When the display freezes, mouse does not move and you can do absolutely =
no
action. Also the last screen with the last values of process parameters =
is
frozen. Only resolution is to the turn the power to the box off and then =
on.
We are using version 4.3 of I/A.
Also there is no weight on the boxes.

Kashif,
The information after the "Panic" is pretty important for determining
what the problem is.
If this has happened recently, take a look in the output of the dmesg
command or in the /var/adm/messages* files and see what the whole
panic string is. Alternatively, go to /opt/crash/{letterbug} and do
"strings * | grep panic" and see what the panic strings have been.
There were some CPU issues with Ultrasparc-II CPUs - you may be seeing
cache or writeback data parity issues - these are CPU related. Other
panic strings may point to memory problems.
64mb of ram seems small for an AW51D - can you email a copy of the
output of vmstat 10 10
in your reply?
Your problem with the display freezing is likely a different issue.
Many users have had an issue with the alarm manager causing the screen
to stop taking mouse/kbd input. If the mouse moves but can't click
anything, try to log in remotely and kill the alarm manager task. If
the screen un-freezes then you know that's the issue. The alarm
manager will restart the next time the alarm button is selected.
There have been a number of Foxboro Helpful Hints and QFs that reduce
the incidence of this problem but I don't know if it is completely
resolved. What I/A version are you at?
I've seen frequent other problems with the 51D series workstations -
they seem to be significantly less sturdy than the other boxes in the
51A-51E range. I've had significantly more power supply, cpu and card
failures in these boxes.
If the boxes are being used on a desktop, ensure that they are not
supporting a heavy monitor. Enough weight on the top of the case when
used horizontally can cause the box to panic or shut down.

Kevin FitzGerrell
