Hello all,

A while ago (10th of december 2001) I reported a problem with the Apache
HTTPD server running on my development server (subject was: "[crit] (98)
Address already in use: make_sock: could not bind to port 80"). After a
short conversation, I came to the conclusion that the fault must be in
the initialisation script. I still hold to that conclusion, and have
found the time to do some more digging.
In the launch script, there's a line 'daemon $httpd `moduleargs`
$OPTIONS'. If I comment out everything after $httpd, httpd doesn't crash
after startup. If I don't it does. If I put the hash (for commenting)
after `moduleargs`, httpd crashes after launching.
If I leave the $OPTIONS in, but remove the `moduleargs`, it doesn't
crash.
Here's a dump of the moduleargs subroutine:
-- BEGIN moduleargs() --
moduleargs() {
moduledir=/usr/lib/apache
moduleargs=`
/usr/bin/find ${moduledir} -type f -perm -0100 -name "*.so" | env -i
tr '[:lower:]' '[:upper:]' | awk '{\
gsub(/.*\//,"");\
gsub(/^MOD_/,"");\
gsub(/^LIB/,"");\
gsub(/\.SO$/,"");\
print "-DHAVE_" $0}'`
echo ${moduleargs}
}
--- END moduleargs() ---
and a listing of the /usr/lib/apache directory:

I am tempted to come to the conclusion that one of these modules is
causing httpd to crash - but I don't know which one. My guess would be
either one of libperl.so, libphp4.so, libdav.so or libssl.so, because
these are in IfDefine wrappers in the /etc/httpd/conf/httpd.conf file
(and, if I am correct in this, are not loaded when no modules are
defined on the command-line).

The Apache version I'm using is still apache-1.3.20-16

My questions:
* Am I correct in assuming that one of the modules must be the cause
of the crashes?
* Am I correct in assuming it's one of the four I mentioned?
* Any recommendations to get rid of this error?

Other things I noticed: Perl is working fine (or seems to be) if httpd
is started without arguments - PHP doesn't work (PHP4 is installed).

Any pointers are greatly appreciated.

Thanx!

Ronald
