I’ve been having a very weird crash while uses ardour for a couple of version now. When I click the export button my computer just instantly shuts off and restarts. I thought that it is possibly my CPU overheating but I’ve not been able to replicate this by doing any other intense processing other than Ardour export. Does anybody have any ideas about how I could diagnose this or test the heat theory with another piece of software?
At the moment I can still export by routing the master our to another stereo track and recording it but this is not ideal.
Im doubtfull that it is an overheating cpu if other intensive programs dont cause the same issue.
First thing to check is what your CPU temp is at to begin with before any crashes, this will give you an indication on how well your CPU is being cooled to begin with.
At idle, my cpu on both cores are around 20C.
You can type “sensors” in a terminal to get a reading of your cpu.
If its not installed then look for lmsensors i think its called.
But i dont think its an overheating issue, sounds more like hardware instability that could be caused by other issues. A bad power supply can cause this. having unstable voltage rails can cause wierd crashes.
Are you using any sort of ALSA to JACK bridge? (ie Cadence on KXStudio). Supposedly it causes crashes if there is any ALSA i/o when Ardour3 is exporting, however to my knowledge those crashes aren’t severe machine killers like yours. I have also had a few versions of Ardour3 go kaboom when setting up the first Export but it then seems to work OK once the settings are established.
the closest i get to that is in Mixbus, when the session takes more than around 35% of DSP - Exporting makes Jackd go nuts, Mixbus stops responding and i have to kill both Mixbus and Jackd, however Qjackctl is not affected.
It is pretty disapointing since that makes me bounce Mix buses to remix them after i’ve De-activated all other tracks and plugins to get Mixbus to take only around 20% of DSP, other than exporting, i get no problems Mixbus runs up to 80-90% DSP no problem… just won’t export.
the alsa jack bridge on my kx studio causes export to freeze, but it doesnt cause any instability any where else, it just causes export to sit ther doing nothing. i can still click cancel and try again. It only works if i disable the alsa jack bridge.
Ill need to mention that to falktx and see if he can work out why its causing problems.
I’m using Ubuntu 13.04 with qjackctl and 3.8.0-30-lowlatency kernel. No ALSA to JACK bridge that I know of.
My CPU at the moment idles at about 50°C with an ambient room temperature of around 19°C, I think I need to redo the thermal paste from what I’ve read about removing and refitting the heatsink. I tested my heat theory using Handbrake to convert a video file. All 8 threads running at 100% and the cores hit almost 100°C (I’m told this is about where throttling hits in) but the computer did not turn off.
I’ve had a look at the system log files but I can’t really see anything that I expect would be causing it. Are there any Ardour specific log files that would be good to view?
It could also be something in your system causing load on your system all the time, like a rogue program or something not behaving properly eating CPU cycles.
But even still my CPU under 100% load when rendering video files never excepps 40c
Check your heatsink isnt blocked with dust, check your fan is working properly. Are you overclocking?
My cpu is only an athlon 64 dual core running at 2ghz so for that the stock heatsink and fan that comes with the cpu cools it fine, but more powerfull cpus with more cores i dont think the oem heatsinks and fans may cope aswell. it may be a good idea to upgrade it to cool better.
Also if your running a high performance system make sure that you have good airflow through the case coming in from the front and being exhausted through the back. I also have a fan on the side of my case which draws are in ontop of the CPU section.
Another quick thing you could check is to try 12.04 on a Live DVD or USB stick incase 13.04 is causing odd problems. 13.04 os bleeding edge and not as stable and also 12.04 is LTS
Ok, I’ve applied the new thermal paste and the computer now runs at about 35-40°C and tops off about 49°C while doing intensive stuff so that seems much better. However, the first time I tried to bounce a project after that the computer just halted and was not responding so I did a hard reset. The next time bouncing down it got about half way and just shut off like before, so I think it is not being caused by heat.
My other thoughts were whether the memory is causing it? I ran a memtest a little while ago for a few hours and it did not show any errors though.
After looking at the logs either side of the crash, my only other thought is that maybe it is something to do with my USB audio card disconnecting or something. My JACK has a horrible habiting of just quitting every now and then without any warning.

I noticed the Sep 13 12:02:21 christie-desktop kernel: [ 32.048371] usb 1-6: USB request error -18: unknown error just before it restarts but I don’t know how to find out which device that is.
I don’t think it’s related to the problem though, it doesn’t look serious. And it doesn’t happen quite “just before it restarts” either, your sys.log shows the computer’s still working 20 seconds later. I’d probably take a closer look at wlan2 myself, although I don’t think that’s the problem either. It looks like you’ll have a lot of fun chasing this one.
I don’t see any device attached at bus 1 device 6. Could it be that the order of devices changed when it rebooted?
Here is the output of lsusb:

I wondered if it was the dirty power in the house but I have just moved house and I am still having the problem.
I’m not sure what the power supply is and because of the way it is mounted I can’t find out without taking the computer to bits. However, when I bought it I did use an online power supply calculator to make sure it was powerful enough. Maybe it’s quality has degraded over time?
I also thought that maybe it is the USB audio card causing it, so I tried bouncing using the onboard intel card and got the same issue.
As the network adapter popped up in the logs a lot, I removed that, disabled networking and tried to bounce but the same thing happened.
Would my RAM have this kind of effect? I don’t know how Ardour works, but maybe my memory can’t handle the bounce and just flops out?
At the moment, I am a bit worried that this constant untidy rebooting is going to damage my SSD
at boot where you can select the kernel you want to boot, there should also be a memtest option, it may take a while though to test all 4gb but that should tell you if there are any problems with ram, but id think it would crashes or freezes rather than just shutting off. But it could be, so test the memery.
My only other thoughts are the north bridge overheating.
I wondered if it was the dirty power in the house but I have just moved house and I am still having the problem.
I hope you didn't move just for that reason :) swapping out components in a PC / DAW to try to fix a problem is reasonable, but swapping your entire house seems a bit extreme :) !
@veda_sticks I ran a memtest for about 8 hours the other day and it said everything is fine. Should I run it for longer? I’ve heard about people running it for days.
What is the north bridge?
@linuxdsp Haha, no I was just moving back to university for the new year.
Does anybody have any other ideas? This is quite worrying as it only happens when bouncing a session in Ardour.
Does anybody know how I can recreate the load of a bounce in some other software?
So far I have found that:
it is not heat (I can run a video converter at 100% CPU on all cores without a problem and no throttling even)
It is not the memory (memtest found no faults).
It is not the USB soundcard (still happens on the internal soundcard when the USB one is unplugged)
The only possibility I can see is problems with voltage (how do I test this? and why would this happen only when I bounce in Ardour?)
Could this be something to do with using an SSD for my operating system? /home is on a 1tb HDD and / is on a 64GB SSD.
Im not sure how you would monitor voltages in linux, it may be possible to configure lmsensors but im not sure how. In the bios it should show you what your voltages are but thats not under load. The only other way is to buy a PSU tester. I saw one on aria.co.uk but then it may not be that.
The northbridge typically handles communications among the CPU, in some cases RAM, and PCI Express (or AGP) video cards, and the southbridge.[4][5] Some northbridges also contain integrated video controllers, also known as a Graphics and Memory Controller Hub (GMCH) in Intel systems. Because different processors and RAM require different signaling, a given northbridge will typically work with only one or two classes of CPUs and generally only one type of RAM.
There are a few chipsets that support two types of RAM (generally these are available when there is a shift to a new standard). For example, the northbridge from the Nvidia nForce2 chipset will only work with Socket A processors combined with DDR SDRAM; the Intel i875 chipset will only work with systems using Pentium 4 processors or Celeron processors that have a clock speed greater than 1.3 GHz and utilize DDR SDRAM, and the Intel i915g chipset only works with the Intel Pentium 4 and the Celeron, but it can use DDR or DDR2 memory.
If it overheats it can cause resets, i found pages on searching that mentioned it causing crashes during games if it overheats so it could be possible that other things could do the same.
also did you try reducing your memory clock/frequency?
Years ago i had the same thing happen but only in games, but i never figured out why until i got a new computer, but my guess is instability somewhere caused by an overheat, or hardware configuration. Try reducing the memory clock and go from there.
You could also try a fresh install, id recomend 12.04 , its a little more stable though 12.04 is still pretty new. Pure debian systems use older software for a reason. 13.04 isnt considered stable.
