Created page with "==Configure Apache for core dump on Segmentation Faults== While trying to debug a 500 error the other day, I noticed that it was giving me a Segmentation fault. > 26619 15:4..."

New page

==Configure Apache for core dump on Segmentation Faults==

While trying to debug a 500 error the other day, I noticed that it was giving me a Segmentation fault.

> 26619 15:44:43 --- SIGSEGV (Segmentation fault) @ 0 (0) ---

To get rid of this problem I was asked to configure a Linux system so that Apache can dump core files on segmentation faults.

===Enable Apache Core Dump===

Now Apache does support the CoreDumpDirectory directive, so our first stop is adding this to httpd.conf file.

Open httpd.conf

vim /etc/httpd/conf/httpd.conf

Add the following line to the Main Configuration Section:
CoreDumpDirectory /tmp/core-dump

Now lets create this directory if its not already there

mkdir -p /tmp/core-dump

Set permissions on the folder so Apache can write to it.

chmod 0777 /tmp/core-dump

You will also want to add the following to your Apache init script

vim /etc/init.d/httpd

Add the following to the top of the script
ulimit -c unlimited

Now we just need to restart Apache web server:
/etc/init.d/httpd restart

How do I read the core dump files created by Apache on Linux systems?

==How to read the Apache web server core dumps ===

Well I am not a developer but they are using gdb and other techniques to analyses the core dumps. Read man page of gdb for more information.

gdb apache2 –core /path/to/corefile
