Multiple programs returning segmentation faults

Hi,
  For the past week, my Arch system has been returning segfaults for ls, pacman, firefox, openoffice, nedit, and rhythmbox (through gstreamer). I have never had any problems before this.
  I have solved the 'ls' problem by doing a 'pacman -Sr /mnt/arch' from a newly installed backup system on the same harddrive, and 'ls' is working properly right now. While I am able to boot into the original system, the other programs are working erratically.
  I have had the same problem with firefox for even the newly installed backup system and am typing this message during one of the random times when firefox is working.
  Having searched on the forums, I read that many programs all segfaulting probably means a hardware error, and I should check my ram, processor, and other stuff.
  So, the question is, how do I check my hardware?
  Here is an strace of firefox in the newly installed backup system.

I hope this helps. I have straces of soffice and rhythmbox also, if anyone wants them.

Re: Multiple programs returning segmentation faults

Hi,
  For the past week, my Arch system has been returning segfaults for ls, pacman, firefox, openoffice, nedit, and rhythmbox (through gstreamer). I have never had any problems before this.
  I have solved the 'ls' problem by doing a 'pacman -Sr /mnt/arch' from a newly installed backup system on the same harddrive, and 'ls' is working properly right now. While I am able to boot into the original system, the other programs are working erratically.
  I have had the same problem with firefox for even the newly installed backup system and am typing this message during one of the random times when firefox is working.
  Having searched on the forums, I read that many programs all segfaulting probably means a hardware error, and I should check my ram, processor, and other stuff.
  So, the question is, how do I check my hardware?[...]

You can try Memtest86+ to check your memory. There's a package of it in extra and if I'm not mistaken it provides a filesystem image that you can boot using lilo or grub.

*Edit*
Fixed the Memtest link

Memtest returned an error when performing test 4. It said 

Failing address - [random alphanumeric code] --- 97.3MB
Count - 1
Err-Bits - 00008000

Other information provided at the top of the screen shows 

L1 Cache - 8K 19706MB/s
L2 Cache - 128K 16812MB/s
Memory - 224M 789MB/s

I don't know if this is relevant but other posts on the forum suggested matching RAM and memory speeds, so I thought I'd record that too.
  Is this the information you wanted? If it is, what do I do to get my computer back to working correctly again?
Thanks,
Ravster.

Hi!

Memtest86+ showed that your RAM is bad. You need to change it. If it is still under warranty, than change it where you bought it, if not than it looks like you should buy a new one. There might be some solutions to disable damaged parts of the RAM (I can't recall where I read about it), but other parts may become damaged also sooner or later.
So I suggest a RAM change.

Re: Multiple programs returning segmentation faults

There's a BadRAM patch, which could allow you to use your defective RAM module. It's not included in any of the official kernels, however, you'd have to patch the kernel yourself.
