Ubuntu crashing

Not sure if it's boinc or something with ubuntu. Just the past couple of days, my ubuntu rig has been crashing. This has never done this before. Rock solid. Anyone else? This is a dedicated crunch. Running 10.10 and the latest WCG approved boinc. Can someone point me to the older logs? Maybe I can find something in there. Also, crunching aides and 3 cep2.

Re: Ubuntu crashing

My three Ubuntu 10.10 boxes are still rock solid, even as I have been pushing them over the past couple of days to see how many CEP2 they can handle simultaneously.

I installed the latest Ubuntu patches a few days ago, haven't noticed any instability from those either. I'm running boinc 6.10.58 x86_64-pc-linux-gnu, installed from the Ubuntu repository.

Which logs are you looking for? The Ubuntu system logs are in /var/log/. The current log is the file called syslog, the older logs are syslog1, syslog.2.gz etc.; 24 hours per log, a week of history.

Cant remember to not ever be able to get to a Terminal with Ctrl-Alt-F1/F6 and then do a few commands to find the logs...

dmegs

top -u boinc

to restart GUI: sudo service gdm restart

BOINC Logs: /var/lib/boinc-client/stdoutdae.txt and other .txt and .old files

and with wifi crashing: sudo service network-manager restart

if the wifi is out, my boinc has a tendency to want to eat through job, so I schedule networking, when I'm there.

The much hated RtFM offers lots of discoveries ;-)

BOINC Logs: stdoutdae.txt

Re: Ubuntu crashing

Looked at all the logs and not seeing anything indicating a problem. It made it through the night without crashing. Guess I'll keep any eye out and see how it will go.

Re: Ubuntu crashing

Changed any hardware components lately ? Unexpected crashes might be due to some transient heat problem. Blown out the heat sinks lately ? Power fluctuations(brownout) on that circuit might be to blame.

I'm shooting the dark here. smile

Re: Ubuntu crashing

Hello,

I have the same problem reported by Bearcat on my i7-740qm laptop crunching only for WCG, and since day 1 of installing Ubuntu 10.10.

I initially thought that it was because of Firefox (if you google a bit, you will find plenty of people reporting this), and I started to use Cromium. Now, I do not recall it ever crashed during navigating anymore, but it crashes every now and then while watching a movie, or - exactly this night - when just running Boinc.

What happens is that when you force shutdown (no Ctrl-Alt-F1/F6 is possible) and then start again, one (or two WUs, like this night) are resetting to zero the progress but not the CPU time. And then when reporting the WUs "compromised" the server is validating them and eventually recognizing the additional time spent processing by awarding more points. No differences between sciences, it happened to me with FAAH, HCC, and now DDDT2.

I do recall Sekerob in the thread 'I am not a Linux Adapt' was saying something about WUs crashing when internet was not available, but this is not the case (although I was also thinking initially this could be the cause, but even asking Boinc not to connect, still crashing).

I think is something related to Ubuntu itself and having nothing to do with Boinc.

Generally speaking, without purpose of complaining or offending anyone, I take the chance to tell somebody my thoughts: from my experience of newbie with Linux, I feel this operating system not ready for a whole no-hassle user experience. Still too much hardware-dependent (I mean not everything is supported), and as soon as you wish to use an advanced functionality, here you go writing lines and lines of code, and good luck with finding them on the Internet, and cross your finger those lines somebody wrote will work on your hardware.
Apart from the crashing, not working despite all the efforts the lm sensors, to control the fanspeed, not working the microphone, not working the nvidia drivers, I had to reinstall the OS three times and then I give up, also Nouveau are not that bad.

Only thing advanced thing working is stopping the GUI! applause

See for example this, on crashing and talking about 'tell me what you hardware is and I will tell you who you are!' biggrin http://ubuntuforums.org/showthread.php?t=1662450

Full respect for Linux on servers and high-end uses, I wish I were a Linux superuser! ;-)

Cheers.

Edit: added details on sciences

Edit2: added link and some details

Re: Ubuntu crashing

Tell you, beyond me, as even when shutdown has utterly stuck in signal 15, still can get into the Ctrl-Alt-F2 through F6 terminals of Ubuntu 10.10. Ctrl-Alt-F1 or F7/F8 screens often listing the bad lines that causes the hang or else run dmegs in terminal.

Yes, jobs get still eaten when the connection between host and router has toppled, not always and happened today to set up a different script run as crontab job, once every 60 seconds, to keep the WiFi alive... the efficiency jumped another 0.1%... can't get it higher than 99.90-99.95% :P

Crashes... get rid of the screen candy. Switch in System > Preference > Appearance back to standard, Nividia drivers the suspect element (now on 270.xx) and Power Management is iffy in Linux/Ubuntu, so except for blanking the screen after 5 minutes, it's off... anyone spinning down their HD's? Don't!

Nope. Nothing added until couple days ago when I installed my ATI GPU from my other rig that got the 6950. Wasn't a whole lot of dust in there while in there but did blow that out. There was a update a few days ago that came out but it's been rock solid since the day I wrote about the complaint.

Re: Ubuntu crashing

Worked very hard to get Ubuntu to hang utterly, not even able to switch to Terminal and succeeded... added back GNOME color chooser and RGBA functionality and a new feature of DockBarX that emulates the same superbar function of Windows 7. Then noticed the external drive USB3 and Wifi light were in stasis. Unplugged them, and Ubuntu resumed as if noting happened. Not even BOINC recorded any heartbeat issues ... just a frozen GUI or was it just the (wireless) keyboard not getting interrupts. The mouse still moved, by hand.

Re: Ubuntu crashing

The only part of these postings I understand is the Latin! I have two machines running unattended, problem-free under Linux (Mint Julia).
