Hello Sunil,
The forum thread was for display purposes in kernel version when issuing the
ps() command + options. Unless your running different kernels between Web1
and Web2 I don't think it applies to your situation.
Did you get any output in the log files with the 'Debug' option turned on?
Is root kicking off apachectl on both boxes? Only super-users can use ports
<1024. Once the first process kicks off, setuid() to apache.

Hello Mike
Thanks for you reply
On the both the server user setting is same. I mean user id and group id is
same.
I mean I added user with the same userid on it (groupadd -g 532 apache;
useradd -u 532 -g apache apache)
I download the source from httpd.apache.org and and compiled it. with the
same option on both the server.
following is the option i selected on the both server while install apache
./configure --prefix=/home/sunil/apache
--enable-suexec \
--enable-module=so \
--with-mpm=prefork \
--disable-mime \
--enable-mods-shared=mime \
--enable-mods-shared=userdir
I done the syntax check and it is OK.
Mike can you have look on this below link he is quite having the same
problem

Hello Sunil,
Who owns the daemons on Web1 and Web2? Are the entries in /etc/passwd and
/etc/group the same for the user/group apache? When you installed apache
did you use the default install from the OS, install from rpm, or install
source and compile?...on both boxes. Run the 'apachectl -t' or 'apachectl
configtest' command to verify the syntax of your config files are correct.
Modify your /etc/httpd/conf/httpd.conf file and change the 'LogLevel' to
Debug to capture errors to the error log, then stop and restart your
daemons. I would then parse the log for info. This may help in identifying
what's not starting.

I start manualy when system boots up.
I am using apachectl script to start the httpd service. which comes with
apache souce.
httpd.conf is same expect IP address on both the web server..
I copied it from web1 to web2 because, on both the server I am running
same site.
I installed same version of apache from souce on both the web server.
Both system are having the same OS version (Redhat 9) except the
kernerlversion.
And logs are shown normal entries and are same on both the servers

Sunil,
Are there any differences in the init.d scripts between the boxes? Are
you calling out a run level script at boot up (i.e. rc3.d, chkconfig
--list httpd)? Web1 is starting correctly and Web2 looks like it's
spawning child processes off of the parent process. Are you calling
'apachectl' or 'httpd' to kick off the daemons? Verify that all the
proper modules are compiled for apache: apachectl -l
Is there information useful in your /var/log/boot.log, messages or
/var/log/httpd/*? Also check root's mail and look through the
"LogWatch" for any discrepancies. I would also look at system
differences between the boxes, like the httpd.conf files, version
differences with the rpm's, things like that.
Good Luck!!!
