[gentoo-user] Computer turn itself off

[Joseph]

I have a box in a remote location (8-core CPU) and it turn itself off during compiling

The box it connected to UPS.  Is it power supply?

Maybe. I have a problem like that when using high processing simulation 
with nvidia-cuda and the power supply protection was unable to keep a 
safe energy level then the system goes off.

But, if the failure happens during compilation time can be a heat 
problem. Install lm_sensors and use something like that: "watch -n 1 
sensors".

If not, if the temperature stay at safe levels, maybe you have a RAM 
corruption. In this case, you'll need to use memtest86++ to check.

Good Luck

Thank you for the feedback, checking the sensors there is what I get:

fan1:           0 RPM  (min =   10 RPM)  ALARM
fan2:           0 RPM  (min =    0 RPM)
fan3:           0 RPM  (min =    0 RPM)
fan5:           0 RPM  (min =    0 RPM)
temp1:        +45.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
temp2:        +98.0°C  (low  = +127.0°C, high = +70.0°C)  sensor = thermal diode
temp3:        +98.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor

I tried to read the lm-sensors again and the compupter turn crash with the readings:

fan1:           0 RPM  (min =   10 RPM)  ALARM
fan2:           0 RPM  (min =    0 RPM)
fan3:           0 RPM  (min =    0 RPM)
fan5:           0 RPM  (min =    0 RPM)
temp1:        +47.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
temp2:       +106.0°C  (low  = +127.0°C, high = +70.0°C)  sensor = thermal diode
temp3:       +106.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
cpu0_vid:    +1.250 V

I'm suspecting it is power supply.

I wouldn't trust these numbers.  You probably need a different/correct driver 
in your kernel to measure your CPU and MoBo chipset readings and/or a later 
BIOS firmware.

Whenever I had such problems they were down to bad memory (some PCs are rather 
particular in only accepting matching memory modules) and also down to a sick 
power supply.

Memetest86+ should tell you after some hours if something is amiss.

The power supply problem will require opening it up and checking for domed 
capacitors.  A few cents later and with a soldering iron in hand you should be 
able to fix any cheap capacitor induced failure.

Of course if the machine is hundreds of miles away, attending to it is more of 
a problem.

Hey, did you run "sensors-detect" and "/etc/init.d/lm_sensors" as root 
before use "sensors"?

As was said, maybe you're using wrong kernel modules.

I went to pickup the remote box and look at it; the CPU fan stop working.  The CPU heat sink is big so in idle mode it could keep up with cooling it but under heavy 
load "compiling anything" the CPU was overheating.

Ha!  So the fan speeds showing zero was true.  :-)

Often they start rattling before they fail.  I found that peeling off the self 
adhesive label in the middle and applying a single drop of thin oil on the 
bearing restores them to rude health.  I have one here which is still running 
quietly for five years since my intervention with an oil can.

I'm real bad to take a needle, like people take shots with, and poke a
small hole in and oil fans that way.  I also do that to those expensive
high speed bearings on my riding lawn mowers.  I've had bearings last
for decades that way.  It is amazing what just a tiny bit of added oil
will do.  ;-)

Yes, zero fan speed and high temperatures should be inventigated before
being written of as misconfigured sensors.

They'd have to rattle pretty loudly on a remote box to warn you of
impending failure ;-)

Given the cheapness of the fan and the price of the component it
protects, is it worth taking a risk?

This is the CPU fan we're talking about here. When I took the lid off my box 
the other day to put new SSDs in it, I was astonished once again at the size 
and complexity of the fan on this i5 chip. Not at all cheap-looking!

Right, but talking about cheapness of components, I had nearly new fans making 
a noise that they shouldn't be making.  I've even returned relatively 
expensive aftermarket coolers because they were poorly manufactured with 
uneven contact surface for the CPU.  What I'm saying is that in today's world 
of mass marketing and el-cheapo manufacturing, where shaving a penny is a 
strategy applied not only on the workers' wages but also on the materials and 
manufacturing process, we are left doing QA ourselves or keeping both pieces 
of whatever breaks.

Permit me a little quibble: we're not doing QA but QC (control). Not at all 
the same thing. QA is defined in the ISO9000 series of international standards.

You're absolutely right of course:  I meant, but didn't express it so, that we 
have to compensate for lack of adequate QA and poor QC.  However, thinking 
about it, I am probably wrong altogether.  Said manufacturers may have both 
processes in place, but implemented with comparatively low acceptance 
thresholds for what we expect.  Ahh!  The joys of globalisation.  :-(

I suggest to inspect the CPU's fan/heatsink assembly periodically.
While back one of my systems  CPU's hinksink was coming
unattached from the motherboard.

Dust is often the culprit on Computers. Just pull the side cover
and blow it out with an air compressor, once a year or so. Dust build up
and also dampen the heat transfer rate (cooling effect) on all sorts of 
parts. So cleaning out the dust allows things to run cool, keeps moving
parts clean and will extend the life of your hardware. This is particularly
acute with the sort of fine dust that builds up inside of computers....

Blowing compressed air on fans make them often "over speed" so be mindful
to only blow on the fans in short bursts. Clean the fans in the power supply
likewise.
