I said RHEL v5.6 (x86_64 architecture), so versions are:

RHEL packaged and patched:
--------------------------
Apache - httpd-2.2.3-45.el5_6.1
PHP - php53-5.3.3-1.el5_6.1

EPEL packages:
---------------------------------
mod_extract_forwarded-2.0.2-2.el5


3rd party (compiled and packaged by me):
----------------------------------------
php-eaccelerator - 0.9.6.1
php-pecl-memcache - 2.2.6
php-mcrypt - 5.3.3
php-sqlite - 5.3.3

mod_jk-ap20 - 1.2.30-1jpp


I suspect it's php too. But how to locate which module is to blame?

It's possible. How can I debug it further? Maybe I should ask on some
other list because I can feel the negativity from your comments... I've
shown with my first post that I'm not lazy and can do basic research.
I'm sorry if you understood my question as an attack on apache project.


Thank you,
