Apache segfault

[Floof]

Hello,

I am experiencing problems with
my apache install :

When I firstly installed everything
on my linux mandrake 8.0 PC
everything worked fine. (including
apache from the Mandrake 8.0 RPMs)
I've been using this config for a while,
but I now experience the following problem :

Each time I try to launch apache, it fails to start.

Upon bootup I have the following message :

Starting httpd: [FAILED]
[FAILED]
[FAILED]
[FAILED]

When I try to launch apache from a command line :

[root@sunrise /root]#/etc/rc.d/init.d/httpd start
starting httpd: [FAILED]
[FAILED]
[FAILED]
[FAILED]

or :

[root@sunrise /root]#httpd
segmentation fault (core dumped)

in /var/log/messages I have :

Jul 10 10:00:42 sunrise httpd: httpd startup failed
Jul 10 10:00:45 sunrise httpd: httpd startup failed
Jul 10 10:00:48 sunrise httpd: httpd startup failed
Jul 10 10:00:51 sunrise httpd: httpd startup failed

And I have nothing in apache's error_log.

Does anyone have an idea ???
I've run out of clues .....

Thanks for any help

Florent.
