Hello,

My desktop specs:

OS : Linux Deepin 2013

Arch : X86_64

RAM : 4096 MiB

Recently when I open Firefox and Google chrome, I get those crashed with the error Segmentation fault. Even when I leave the browser open with several websites, suddenly it crashes with segmentation fault.

A note: Once I was unable to launch Google chrome browser. So I entered in to Terminal and tried to run from there. All I got was Segmentation fault. Then I rebooted the machine and I can launch Google chrome successfully and this time it didn't give any segmentation fault. So it happens at random times but very often.

Also, I can launch any other applications such as Terminal, Libreoffice, Nemo without any crash. Only with these browsers.

Steps I followed to debug the issue:

1. Disabled all the addons and ran firefox in safe mode.

2. Ran command : strace firefox to trace the issue and it gave only Segmentation fault.

3. Ran Memtest86+ to test the RAM. My RAM chip passed the test with no errors.

This issue is not reproducible, but it occurs at random times but very often.


Yet, I get Segmentation fault.

I couldn't get in to work with these segmentation fault errors and I lose my precious time and the work I done when the browser crashes. Please help me on this issue.

Thanks.

For added information on the issue please see post #17.

I used to have errors like this, check if you have correctly installed the video drivers (yes, its odd but installing the right ones did the job)

I have the default video drivers installed. Also I have the latest system updates installed.

Any help on this? I'm keep getting irritated due to this segmentation fault. I even re-installed OS and this time I installed Ubuntu 12.04.3 LTS and the issue persists. I think its hardware issue than software issue. Whats your idea? How to debug it?

if only firefox (and chrome) crashed it could be hardly a hardware issue. You may try to analyze coredump to get some more info about it.

Now I found that even other applications are crashing due to segmentation fault. I couldn't open synaptic due to segmentation fault. Only after reboot I could access it. Even if reinstalled another OS and it also give the same error means, I think it must be hardware issue.

How to get core dump?

Usually that will automatically created in case of segfault.
You may try memtest to check memory.

I already ran memtest and the RAM chip passed the test. I will run it again for you and will report.

HOW did you install firefox ?
it is already installed by default on on the lts ubuntu it "should" be the OLD lts firefox 17.0.7 or .0.8 or the current 17.0.9

or

did you manually put firefox 24( now 25) on the machine

Firefox version 23.0 was present in Ubuntu 12.04.3 LTS and I just updated using synaptic.

Btw, now most of the apps in the system gets crashed due to SIGSEGV . So I guess it is a hardware issue than software issue.

a bad drive is a likely issue

if many things can not find libs that ARE installed then it could be bad sectors
-- but that is a guess

what is in the system logs ?
/var/log/????

about segfaults. You may try to collect coredumps and check them. There are two possible cases: 1. you will find similar coredumps, the segfault occurred on the same place. It means possible driver problem. 2. you will not find similar dumps, the segfaults occurred on different places, in different libs. It means possible hardware issue.

so it looks like a hw error: RAM, HDD or ?. You can check smart info too.

Ok. I checked the RAM again using Memtest86+ but no errors came. It is same with HDD (no errors). Still I get segmentation fault. I do not know what causes this issue.
