 Segfaults are usually (for me anyways) a non-existant thing. The only time
 I've had them is with flaky RAM.
 
 You're not going to like the sound of this, but I'm suspecting hardware
 issues here.

Another possibility is overclocking the cpu. I had this problem quite 
often 2 years ago. reset the cpu speed to its spec solved the problem for 
me.

I did rpm -Va yesterday. I don't recall if it was done before or after

failed to check the XFree86-libs). Anyway, the output from rpm -Va shows
no sign of my system being compromised.

 also check that your cooling fans are working, and that the case vents
 are not clogged.  I suspect a cooling problem, but that should show up
 in windows more then Linux, or a memory problem.  Memory problems tend
 to show up more in Linux then in windows because Linux tends to use all
 memory.

I looked at the recently redhat kernel update package (released last
week, 2.2.19). It said it fixes minor problem in virtual memory. I wonder
if this means that my kernel (2.2.17, also from redhat updated) is having
this virtual memory problem that causes any program to segmentation fault
randomly.

Here is the gdb -c core output. As far as I remember it doesn't matter
what program segmentation fault, the output of gdb -c core is always
(I have checked at least more than 50 of them).

Core was generated by `lynx'.
Program terminated with signal 11, Segmentation fault.

never ending segmentation fault problem on redhat 6.2

2001-04-23 Thread fang

Hi,

I am running redhat 6.2 with kernel-2.2.17-14 (from redhat updated
kernel). For the past few weeks, I've been experiencing segmentation fault
problem and it got really bad over the weekend. The segmentation fault
problem I am talking about has nothing to do with any local program we
have here. It just occurs when we run some simple unix command, like ls,
man, pine, etc. Anyone knows why this happens?

My first suspicion is these commands either have been compromised or
corrupted, but then again sometimes they just run fine.

My next suspicion is there may be some bad spot on the memory, but again I
did some heavy running jobs under windows and it ran fine too. If there is
bad memory spot, one of these process should have hit it and die already I
think. (The jobs I gave windows to run were big enough to eat up my tiny
64M of memory and more for sure.)

Another note, I eventually reboot the linux system (today) and it seems
that after reboot, this segmentation fault problem doesn't occur as often.
I wonder as time goes on, it may resurface again.
Any suggestion on what I should do now? Thanks

Jimmy

So, you can get the ssh login prompt. If this is the case, then I don't
think /etc/hosts.allow/deny are the problems. You won't get the ssh login

 And in this case, it's probably a CD-ROM drive.  I'd check the disk for
 scratches, and if you're trying to dd something off the disk, verify you're
 using the correct blocksize.  If all that checks out, try using another
 disk; if you get the same errors, your CD-ROM may be in need of repair/
 replacement.

Another possibility is flaky power supply to the drive or bad connection
between the IDE cable and the drive. At least that is what happened to my
computer. Everytime this happened, I just open the computer and push the
connector firmly and the problem goes away.

Re: 4.72 (was: rant F****ng fed up with Netscape 4.6x!)

I have java and javascript turned off and netscape 4.71 or 4.72 doesn't
crash on java-related site. However, my complain with netscape 4.71 is
this. It sometimes (seems randomly) will go into this cpu-hungry mode and
consume the cpu at nearly 100% for several minutes (usually 3 minutes or
more). During this period, I can't scroll, click or do anything at all
with it. The whole page just goes blank. After that, everything is normal
again. I had the same problem when using redhat 6.0 and netscape 4.5, but
it happened less less often. Anyone has the same problem?

My experience with gnome (on redhat 6.0) was that it initially ran fine,

this problem. Is this true?
