My box has in the past 4 hours, locked up three times. It doesn't appear to be temperature as it has stayed about 40 degrees with a max of 46 ... which seems about right...doesn't it? And it should reset from the Bios when it overheats.

It's an Athlon 64 3800+.

I don't even know where to start looking.

EDIT: Further Specs

CPU: Athlon 3800+
Video: nVidia 7300GT
Tuners: Hauppauge PVR 150 (x2)
Ram: 1gb
HD: 160gb (Forget brand...but I seem to recall it being SATA)
KMyth: R5F1

Are you using a no fan video card?

Yea, but this same machine, on a prior install had no problems in the past. So it leads me to think software...

Though, looking at the rrd graphs, it appears the HD spiked with writes around the time of the crashes.

Not sure what would cause that.

ssh into the box and leave top running in that window, or use the batch mode option to generate a log file of activity. That will help you see what's going on on the box when it barfs. I'm going to guess that it's something like a DB update or a transcoding job if disk IO spikes... Although it could just be trying to write a really big core file...

I got top running...hopefully I can catch what is causing this.

Though it appears Mythstream of a shoutcast stream doesn't even make this machine blink. I'll have to schedule a show to record and start watching it while it's recording...that seems to be when it happens.

Now that I think about it...it could be possible it's because comm flagging is on...

So it just did it again, my machine is recording on both tuners, and I was watching an old recording.

Comm flagging wasn't even happening at the moment according to top, here's the first few items in the list



Code:
top - 20:06:54 up 1 day, 19:25,  1 user,  load average: 0.88, 0.50, 0.24

    2 root      RT   0     0    0    0 S  0.0  0.0   0:00.00 migration/0


CPU usage was only 18%.

It must be something else...

Perhaps you haven't enabled the optimizations for the hard drive? In the /etc/init.d/bootmisc.sh
Code:
# enable DMA
/sbin/hdparm -qd1c1u1m16 /dev/hda

I am having simular issues, though I haven't tried loading my system down as such. However, just watching a recording, I can watch somewhere around 5-10 min (I'll time later when I get a chance) and the video stream just locks up, in fact the entire system appears to lock.

As stated when I get a chance I'll time it, check the top output, and try seeing if the underlying system is still running or what.

BTW, here is what was listed in my bootmisc.sh

Code:
# enable DMA
/sbin/hdparm -qd1 /dev/hda


I have added the other options you listed to that file, and I will see if they make any difference.

It's the exact same issue that I'm having.

Perhaps posting details on your hardware. Have your read the troubleshooting entry on the wiki? If it is locking up when what live tv, I'd support an issue with your tuner card. However with no details, I cannot advise further.

Looking at the specs on the system when I started and now.. I've changed quite a bit.. here is what I know for sure:

Specs:
Athlon 1.6ghz
512 Mb ram
80 GB IDE HDD
Ensoniq 5880 sound card.
pcHDTV HD3000 HDTV [card=22, autodetected]

NVidia video card (64mb PCI with tv out I believe, can post details later)

Just realized as I was looking through my messages and dmesg logs (looking for the capture card information) that I've got a couple of excess usb devices I can take off, though they shouldn't be interfering (namely logitech rumblepad controllers)

Hope that helps.

Amos

ps. I'm not sure if it locks up watching live tv, as I usually dont watch live tv on the system. Also, I was able to edit a movie to manually flag commercials (however I keyed my way through the movie rather than watching it like I had wanted to do) and then transcode it to remove cut-list and reduce file size)

Good news... The syntax the tophee suggested above seems to have done the trick. Was able to watch at least 15 minutes of recorded video after making that change, and re-booting.

Now, I think I may have some corrupt tables in my mysql database. Earlier today I noticed the "programs" table needed repaired and did so so that I could do searches in mythweb. So, that leads me to believe that another may be corrupt as well, however I'm not 100% sure. One other reason is, when watching recordings, before if I would back out of them to the selection screen, then come back in it would remember where I was when I backed out (sort of like a pause/resume feature). Is this something that is no longer going to work, or is it, as I'm thinking a mysql table that isn't loading, and thus not populating to hold this data?

btw.. the video card is an Nvidia Geforce 4 mx 440 64MB PCI.

So far, so good. Thanks.
