Recently, one of my machines (running F8) has started beeping and I
can't figure out the reason why. After watching it this morning,
I've
noticed that every 30 minutes it seems to beep 20 times. It almost
sounds like a BIOS beep, but the machine has 177 days of uptime (and
counting). So, I'm wondering, what will cause 20 short beeps? My
wife describes it as almost sounding like a flute. I figure its got
to be a warning of some kind. The motherboard is an ABit NF7-S2 with
an AMD XP 2600+ CPU and 1.5GB of RAM (3 512MB sticks).
apcupsd says that my battery is still good (100% charged, 32 minutes
est runtime) and the last "event" was on 10/13 (Low Line Voltage).
I just checked, and the sound is being output through my computer's
sound card's speakers, though that motherboard has integrated audio
and I think it is set up to do "pc speaker" through the computer's
external speakers.
If you run acpi, you can check temperature and fan speeds etc. It sounds
like your Bios may be warning you of over heating or something.
I checked my temps, CPU=37c case=30c. Case is in the blue, CPU is
only half red. My disk drives are at 42c (1/2 red as well) and they
have a fan blowing over them.
If you're running software or hardware raid it may also be a symptom of
a bad/degraded RAID system.
Nope, no RAID.
Basically, do a full system check.
I blew all of the dust out of the cabinet, out of the fans, out of the
power supply (and there was quite a bit of dust!). Also, the cabinet
side is open so its not baking in there. Temps look OK to me, airflow
should be free. Room temp is about 20c.
I'm not sure where else to look.
I would check out google on the issue as suggested, also look through
CRON for all users to verify that nothing strange is in there, or
something isn't tripping it off. At the very least it may be something
different than core temps, since some systems have memory temp ability,
as well as on-die versus on chip temp monitoring. From all you have
said, I would focus more on CRON and validate that what you have
installed on the system isn't doing something silly.
On the other hand, it could just be missing its dust blanket ;)
Silly idea, but have you checked /var/log/messages or dmesg to see if
there are error messages that correspond to the beeping incidents?
Also check root's mail file to see if perhaps one of the cron.hourly
scripts is running that's triggering it.
