Segmentation fault

Hi, community

My computer is running under Fedore9
Yesterday I turned it off and this morning find out that chmod doesnt work
It doesnt work fo any file even under root account it just says

Code:

[mabp@mabp ~]$ chmod a+x 1.txt 
Segmentation fault

even without parametrs it says the same

Code:

[mabp@mabp ~]$ chmod
Segmentation fault

i tried to scan and repair my file system with e2fsck

Code:

[mabp@mabp ~]$ /sbin/e2fsck -p /dev/sdb1/

but without any changes

what can be wrong with my system?

PS sorry for my poor english

 

You need to run fsck as root. Probably best to boot into single-user mode, or even a rescue disk might be needed as the filesystem being checked cannot be checked while mounted. Check all linux partitions except swap. chmod (in /bin) is dynamically linked, so the problem could be in one of the library files (in /lib) which could be on a different partition.

Your problem could also be caused by some bad RAM. If you find nothing wrong with your disks, try running a memory testing tool such as memtest86+. I'd suggest you run it continuously for nothing less than 24 hours for a reliable test, unless it shows errors sooner than that.

 

i did so at first time

inconclusively

this too

RAM test is OK

Is there any way to reinstall chmod?

 

Like ralic I think it's a hardware problem, but it's hard to tell which part it is. Could as well be the mainboard or anything else.

 

may be this will help to tel what is the problem

i dont know what means this line

but i dont like it

 

Does /etc/ld.so.preload exist?

 

No it doen't
but i dont know how to create (generate) new(((

 

I did the same strace (but on ubuntu). They look very similar. Where yours crashes, mine seems to start doing locale activity.

Maybe between reboots you have done something that has messed up your locale configuration?

Can you check your locale setup and see if it is working or broken?
I'm not a locale expert, but

Code:

locale -a

seems like a useful test to check if it's working.

I have it too and mine works. Probably not important for this particular problem.

 

Code:

locale -a

return long list of locales

 

Ok, probably not that then.

Sorry, not sure what else to suggest. Maybe someone can help you re-install chmod on fedora...
