I shorted out the problem .Many people has said its due to the
tempreture or the cooling fan and its true. Actually the problem is with
the temperture . There were some books next to the Ultra 1 m/c (next to
the fan of the sun m/c) . Due to which it was become hot. Many people
have replied . Thanks to all who all gave the information, specially to
I checked /var/adm/message and found that there is a warning mesg.
called "Thermal problem Detected".

Below are the replies I got to the above problem.

Have a look at your /var/adm/messages file. I'm quite sure you will
find a message like "Thermal problem detected". This happens if the
internal fan mounted directly upon the CPU is not running (or at
least is not running fast enough). We have replaced 20 % of these
fans in our Ultra systems within the last 6 month.
You should make sure to get a "new" model if you get a replacement.
The new models actualy have the same part no and revision than
the old ones, but you can distinguish them by counting the wings.
The old ones have 5 wings, the new ones have 7 or 11.
Hope that helps

Sounds like you have enabled the power conservation
features. If the workstation determines it
has been idle for too long, it can shut itself down.
Alternately, if the machine is oveheating
due to a bad fan, it would also
shut itself down.

Did anyone turn on the power management feature ?

Look closely in the messages file. If it complains about temperature,
Sun and have the CPU fan changed. Some early Ultra 1's had bad CPU fans.
You could open the lid and see if the tiny fan on top of the CPU is
