Dear All,
In a previous message I alluded briefly to unscheduled, unwanted, and

much information to share about what exactly is happening.
The system is an Oracle db server with 160MB of RAM, two 75Mhz superSPARC
processors, and a lot of nerve! :-) It's a SS20 that's got two SSA100s
tacked on as well as tape drive (XL), CDROM, floppy, you know the story.
Oh, and it's running Solaris 2.4.
In the past two months, the system has spontaneously rebooted (better than
spontaneously combusting, however) four times without, to my eyes, giving
much of a clue as to why the shutdowns occurred in the first place.
Prior to the startup messages in /var/adm/messages there is absolute silence.
Any clues would be appreciated as well as questions of clarification as I
understand this is somewhat sparse information to go on.
Thanks for your time,

------------------------------- Begin Summary ------------------------------
What I gathered from the many folks who replied so helpfully to my message
was that I was experiencing a problem with my power supply (either the UPS
to which I was connected or the power cord itself). With these pithy
considerations in mind, I descended upon my UPS (which I neglected to mention
in my earlier post -sigh-) and discovered, to my horror, that we were
operating at its nether limits. It is rated for 400 VA and we are using
something nearer to TWICE that number. Oh well. *smiles*
Voltage Amps (VA) can coincidentally be calculated by multiplying the
operating voltage (typically a value between 100 and 240 V) by the amount of
current drawn by your equipment.
For instance,
SPARCstation 20: (120V) x (.6A) = 552 VA
Sun 21" monitor: (120V) x ( 3A) = 360 VA
------
912 VA
The voltage and current values can be referenced along the backside of your
equipment. On a Sparc 20 look to the far right, near the power switch (be
careful!). It is a metallic gray label. On the accompanying monitor,
look towards the leftward side of the metallic label blazoned across the
back.
Left and Right are relative to the UserEye View(tm).
As for the most recent reboot, it has now been traced ignobly to a power
surge caused by a weekend carpet cleaning.
In the interest of completeness, I have included the full text of the
replies I received as a MIME attachment.
I hope someone finds this summary useful.
Thanks and take care,
Linda Maepa

Check the permissions on
/usr/sbin/init
/usr/sbin/reboot
/usr/sbin/shutdown
Do "others" have read or execute permission for these files? (I think
read permission is just as good as execute permission, because if they
have read permission they can copy the file to their home directory or
/tmp and the copy they made will be owned by them, so they can then
change the permissions on their own copy and execute it.
Do you have a UPS ? Power fluctuations or momentary blackouts could cause
unscheduled reboots.

What info does the last(1m) command provide? Were there any users
logged in on or around the time of the reboots? What about logged
shutdown or reboot entries shown by this command? Do the reboots happen
on or about the same time of day? Could it be a power problem?

you can enable crashdumps to see if there is such a thing -
by uncommenting the crash/savecore lines in /etc/init.d/sysetup
if there are crashdumps put into /var/crash/`hostname` then at least
you will have something more to look at

Hello Linda,
Just seen your news... Please take my words with a grain of salt
I can only offer you my experiences with my humble Sparc5 (Sol 2.4).
(I have no expeience what so ever with your equipment, mind you)
1) reboots: do you have jobs being scheduled ?
This is a very remote possibility, but just pondering over
every possibility.
Reboots do log things on my Sp5. Are you familiar with
init levels, and "rc" start up scripts ? You may wish to
take a look at the "/etc/rc2.d" directory to add few lines
of code to one of the start up scripts to see.
Have you checked your "dmesg" (which is also in "messages"
files) ?
Are the reboots happening during a certain job/activity ?
2) Driver problems: I read awhile ago that these messages were
innocent enough to ignore with Sol. 2.4. Below is fraction of
the "messages" file from my system.

Linda,
Try the following:
o.Use another power outlet for the system(change the power chord also).
o.Ensure proper ventilation(eg: check the FANs are working in the system SMPS)
o.Re-seat the memory modules.
o.Still the problem exsist,Replace the SMPS of the SS20.
I had faced the similar problem and it was a SS20 SMPS ! who caused!
Good luck.
Ps:Take immediate backups.Your HDD filesystem may crash due to these reboot!!

Dear All,
In a previous message I alluded briefly to unscheduled, unwanted, and
apparently human-independant system reboots. I unfortunately don't have
much information to share about what exactly is happening.
The system is an Oracle db server with 160MB of RAM, two 75Mhz superSPARC
processors, and a lot of nerve! :-) It's a SS20 that's got two SSA100s
tacked on as well as tape drive (XL), CDROM, floppy, you know the story.
Oh, and it's running Solaris 2.4.
In the past two months, the system has spontaneously rebooted (better than
spontaneously combusting, however) four times without, to my eyes, giving much
of a clue as to why the shutdowns occurred in the first place. Prior to the
startup messages in /var/adm/messages there is absolute silence.
Any clues would be appreciated as well as questions of clarification as I
understand this is somewhat sparse information to go on.
Thanks for your time,
Linda Maepa
PS: Once again, if you could email me direct, it would be much appreciated. I

Cheers:
Hmmmm... could be it went into a panic because of not enuf swap space
I believe I've heard of this in the HP systems...
might want to check swap space to see if you have enuf, especially if
you have a lot of processes running..

It is difficult to diagnose what is going on with your system without a history, have there been any hardware, software or patches added lately? Check backwards to the latest change. If the problem on your system is not being caused by any of the above installs, a first step would be to install the latest kernel jumbo patch, I think that they are up to rev 36...Another option to take if after you have installed the patch and the system is still burping, you can activate savecore in the file /etc/rc2.d/S20sysetup and do a diagnosis of the core file to pin point the problem....

Dear All,
In a previous message I alluded briefly to unscheduled, unwanted, and
apparently human-independant system reboots. I unfortunately don't have
much information to share about what exactly is happening.
The system is an Oracle db server with 160MB of RAM, two 75Mhz superSPARC
processors, and a lot of nerve! :-) It's a SS20 that's got two SSA100s
tacked on as well as tape drive (XL), CDROM, floppy, you know the story.
Oh, and it's running Solaris 2.4.
In the past two months, the system has spontaneously rebooted (better than
spontaneously combusting, however) four times without, to my eyes, giving much
of a clue as to why the shutdowns occurred in the first place. Prior to the
startup messages in /var/adm/messages there is absolute silence.
Any clues would be appreciated as well as questions of clarification as I
understand this is somewhat sparse information to go on.
Thanks for your time,
Linda Maepa
