Summary: [mod_log_config] Piped Log scripts process cause warn
Product: Apache httpd-2
Version: 2.2.15
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_log_config

Hello ;
When I do an 'apache2ctl gracefull', I get following warning in my apache
error.log:
[Sun Aug 22 14:46:00 2010] [warn] long lost child came home! (pid 10436)
After some avestigations, I found that it's the'mod_log_config' module that
cause this issue when we use Piped Log. To show, the problem:
'ps aux' result before do the gracefull:
root 8511 0.1 0.4 6824 4256 ? Ss 14:18 0:03

/usr/sbin/apache2 -k start
Here, you can see my main Piped Log script process (pid 10502) and the second
(pid 10504) that is the background process from (pid 10436).
When I do the graceful, I get the following:
[Sun Aug 22 14:52:50 2010] [notice] SIGUSR1 received. Doing graceful restart
[Sun Aug 22 14:52:51 2010] [notice] Stopping ispCP Apache logger (pid 10504)

[Sun Aug 22 14:52:51 2010] [warn] long lost child came home! (pid 10502)
[Sun Aug 22 14:52:51 2010] [notice] Starting ispCP Apache logger (pid 10579)
Note: Log lines for the logger come from my logging script (Added to show the
problem).
After the gracefull, my 'px aux' result is like this:
root 8511 0.1 0.4 6824 4256 ? Ss 14:18 0:03
/usr/sbin/apache2 -k start

Ok, it's just a warn but I think that should be solved. I've tried with
alternative syntax (Shell not involved at all) and the same problem occurs on
the main process.
My system:
r...@ispcp:/etc/apache2/sites-available# uname -a
Linux ispcp 2.6.32-5-686 #1 SMP Sat Jul 24 02:27:10 UTC 2010 i686 GNU/Linux
The involved SHELL:
r...@ispcp:/etc/apache2/sites-available# ls -la /bin/sh
lrwxrwxrwx 1 root root 4 21 août 07:11 /bin/sh -> dash
The Apache information:
r...@ispcp:/etc/apache2/sites-available# apache2ctl -V

Thank a lot if you can solve this problem.
