<pre wrap="">Hey all,
I have a master backend that has been running .21 fixes for a few months
perfect. As of a couple nights ago it started hard locking up over
night. This machine only runs myth and its DB. The best guess I have
had so far is maybe it has to do with mythfilldatabse running grabbing
data from schedules direct. There is nothing in the log files to help
out. My only guess on when it is going down has been from gaps in log
files starting between 1 and 4 am. I tried running a --refresh-all a
little while ago and it appeared to finish ok, but about 30 minutes
later I realized the machine had locked up again. I am not sure exactly
when the fill finished and how long until it locked as I got sucked into
work and missed it finishing. I ran a straight mythfilldatabase and all
was fine, and am running another --refresh-all now to see if it will
happen again.
Based on the temp logs it is not over heating. Once it is down there is
no ping response or lighting up of caps key on KB or anything.
Completely dead.

<pre wrap="">It is very difficult for a user application to take a machine out (not
impossible, but pretty rare, it requires either a kernel bug, or the application
to use up all of memory).
If you are running at runlevel 3 or running X I would start running runlevel 3
and don't run X (if you can) and see if you get any useful kernel messages when
it crashes, I expect that you might, but they will likely vary from crash to
crash, it is very likely this is some sort of hardware issues, but you may get
kernel messages that will point to one piece of HW or another.
memtest might be a good start, as memory is one of the most likely failure items.

<pre wrap="">Good idea killing X so I can hopefully see kernel messages. As stable
as this machine has been for years, I would hate for it to be a
hardware problem, but it has to happen eventually right. Just been
surprised we can watch hours of HD Olympics during the evening, then
it crash overnight while idling. Was planning on running a memtest
this evening and hopefully that comes back clean, or bad so I know
what is wrong lol.
Thanks

FYI. I had LIRC-USB ( MCE - USB remote control receiver ) hard locking
my machine a while back.
Unplug any USB devices overnight and see what happens.
Eliminate what you can. Power supply , etc.... services, part by part
and see.

Looks like one of my processors decided to start erroring out after
years of great service. Hours of Memtest86+ came back clean, but
prime95 gives me errors after less than one minute. Box has been
running strong for many many years (Dual Athlon XP-M @ 2.3Ghz) More
than enough for a backend, but guess it is time for an upgrade anyway.
Might mess with removing the OC, but not sure it is even worth the down
time right now.<br>

Thanks for the help,<br>
