I posted the following message on this list:
I have a bunch of Ye Olde Classic/LX/SS10s and some of them are exhibiting
a strange problem. Namely, the systems in question are dying from lack of
attention. If a sparc has not been used for a couple of days it seems to
die quietly. The display goes blank, and does not respond to kbd or mouse
activity. The system does not respond to ping either, so the system is
really dead. On the other hand, sometimes when I powercycle the system
it does not fsck the disk, so it seems to have gone through a proper
shutdown. I have played around with /etc/power.conf and the dtpower
utility to no avail. I have disabled autoshutdown, and in desperation
even disabled the powerd daemon. I still see this behavior from time to

Many thanks to the following for their prompt reply:

It turned out that Sun has a patch for this problem. I have applied the
patch and in the last one week the problem has not surfaced. I would like
to express my sincerest thanks to the readers of this list for quickly
pointing me to the right direction. I have attached the description of the
patch at the end of my message.
