Complete Freeze ubuntu 14.04

[Mago Nick]

Hello everybody,
I am experiencing an odd problem.
After a while of using my desktop computer it freezes completely. I have found no solution but to use the reset button on the case.
The thing that makes it hard to track is that is seems to be completely random.
I do not even know where to look to find some information.
I will start with some basic info

Ok.

First question - is this a GUI issue only? Can you connect to the system via ssh over the network? A GUI lockup happens much more often than a complete OS lockup. Troubleshooting is different.

Also, what does dmesg and the syslog show? The trick to access these post-lock-up is to boot off alternate media, mount the /var/log storage and view the files without booting the installed OS.

[Mago Nick]

Hi,
Thank for your fast response. It seems to be a full OS freeze. I was listening to some audio when it freezed and also the audio stopped. I did not do how you suggested, as soon as it freezes again I will save the logs.

[Mago Nick]

Hi,
Since the problem showed up twice today I had the occasion to gather the information you have asked. I added in the first post so it easy to find them for the other users.
thank you
Andrea

[TheFu]

Thanks.

I don't see anything wrong in those files. That's good and bad. Good because some hardware doesn't seem to be breaking. Bad because we have to guess at answers.

If you are willing to post more data, I've created a system info gathering script. http://blog.jdpfu.com/sysinfo Just post the URL created. Mainly want to know the amount of RAM and swap use. I found on a low-RAM system that lockups happened due to out-of-RAM situations. By increasing the swap partition, those lockups all stopped. Completely.

[Mago Nick]

Hi the link does not seem to work.
The ram is 32GB and the Swap in use is 0.
If you would like me to execute any command to gather info, I am here.

Probably is not really related to the desktop environment as I thought. Should this conversation be moved in a more appropriate place?

[TheFu]

0 swap? On a desktop? Don't think I'd do that. 32G? Really? None of my servers have that much RAM, but we don't run windows or geospatial DBs either.

$ head /proc/meminfo
$ free -m
Please post the output from those cmds. I'd be really surprised if more than 4G were used.

BTW, my last "desktop" build cost US$146 and easily runs multiple VMs.

Also checked the reverse-proxy logs. Doesn't appear that anyone hit the link today besides YandexBot. Can you tell if it is a DNS or routing issue? I know that some less-than-open governments have decided to block my little Linux blog. Don't know why. I only complain about my government ;) and there isn't any offensive words on there that I know.

[Mago Nick]

I am a researcher in robotics vision, that's why of so much RAM.

I am afraid I made a mistake there are more than 60GB of Swap.

Follow the outputs of the commands you asked

[TheFu]

While not likely an issue, that is a bunch of memory (combined RAM/swap) for a desktop. Under 3G used. Any GUI programs being used that monitors memory use? Do you have any monitoring setup like monit or munin that could show issues just prior to the crash?

Any warnings or errors in other log files? Just grep.

[Mago Nick]

HI,
The only application that gives me some information about the system is the Xfce4 applet "xfce4-systemload-plugin 1.1.1".

I checked the log, but I did not find anything strange. Since I might be wrong I attach them. I had to upload on pastebin since they were to big to either be pasted on a message or to be uploaded as attachment.

By mistake I have edited wrong the first post, is there any way to retrieve the old post? I have been working far too many hours ](*,)

EDIT: recovered first post, thank you google cache

[Mago Nick]

It happened twice today. I am running out of ideas.

[Mago Nick]

A small update.

The situation was getting worse and worse so I tried a fresh install of Ubuntu 14.04, downloaded from the official website.

It did not solve the issue. However, now I can track the problem a bit more. In fact, it appears every time I run a ros-based (see www.ros.org) and openCV application. Is systematic, every time I run it the system completely freeze.

The code is not mine, but among all the users I am the only one that is having this problem.

Might this be caused by the nvidia drivers?

[Mago Nick]

I have found this thread http://ubuntuforums.org/showthread.php?t=2257257 that seems to address my problem, I disable the option, but it keeps freezing, I will run a memtest during the night to see what happens.
Any suggestion is welcome,
Andrea

i am having the same problem. my desktop will just lockup and the only fix is a hard restart. ubuntu mate 14.04 LTS 64bit. / core 2 duo e6400 / 3.0 gb ddr2 / nvidia 7300 le pcie / hp- pavilion d4650y . tried all of the nvidia proprietary drivers which makes it worse so back to open source driver.

Hi,
actually my pc froze also during the memtest run on parallel on all the 12 cores. I had the suspect of faulty hardware and I had the computer sent back to the customer care. Apparently that solved the problem. I am waiting for the complete report of the repair to have it confirmed, though. If nothing happens until friday I will mark the question solved.
@Poorguy: About your case. I suggest you to open a new discussion and add infos gathered from the logs as well.
Thanks
Andrea
