HELP PLEASE! Apache Segmentation Fault

gabriele_101 · 07-31-2003, 09:59 PM

My apache 2.0 error log looks like this:

Code:

...

And it goes on and on and on.

I've searched high and low and what I see people saying is that it's most likely a memory hardware problem. But I only see it in apache, it's causing performance issues, and the memory checks out OK at startup.

I really don't know if I can afford to try new memory configurations if that is the problem.

How else can I test my RAM?

I have an Abit IS7 MoBo that takes PC3200 RAM (DDR 400) but I'm using PC2700 RAM in stead (could not afford the PC3200 yet). I don't know enough to fiddle with the BIOS settings for the RAM and the docs from ABIT are absolutely useless unless you're an expert in hardware.

I've posted already to the Linux - Hardware forum, but no one answered!!!!

SOMEONE HELP PLEASE!!!

Thank you.

I don't think it's faulty hardware :)

Maybe your apache doesn't match your
glibc or something like that. What distro/
version are you running, where did your
apache come from, how did you install it?
What other modules did you get for it?

Cheers,
Tink

P.S.: If you really think it's the RAM, go
to www.mondoresue.org and download mindi.iso,
burn it and boot of it ... it has memtest as one
of the tools on boot.

Thanks for the reply. As for what versions:

Apache: Server version: Apache/2.0.40
Server built: May 20 2003 10:15:29

It's the run-of-the-mill apache installed when doing a RH 9 install.

I've updated the kernel to 2.4.20-18.9, but I have to admit I don't know how to check my glibc (or any other rpm installed libs/programs) version or anything of the sort. (man rpm is useless).

I cannot be sure if there is something in specific that is causing the error, but is seems to happen when running either perl CGI or PHP script. Server side includes and normal page feeds don't seem to cause it. I'll be taking the whole thing off-line tomorrow to verify that statement.

I will also attempt installing 2.0.47 tomorrow to see if it will remedy the problems, and since there are some severe security issues with versions prior to 2.0.47 and the bug fix list is rather long. Unfortunately the only seg-fault fix mentioned has to do with memory mapped NFS files (and I don't mount any NFS partitions on this server).

Thank you for the mindi.iso link, I may try that too if the apache update leaves me in the same place.

Found the magic rpm command:

Code:

rpm -qa

Latest update, if that helps at all. I ran:

rpm -qa | egrep -i 'php|glib|http|perl' | sort
