clean_child_exit result in Program terminated with signal 11, Segmentation fault.

[Stanislav Davydov <stas.davydov@xxxxxxxxx>]

Hello, everybody.

I am using my setup of Apache for rather long time and all the time it spoof my logfiles with messages like:
[Wed Aug 15 13:37:55 2012] [notice] child pid 7415 exit signal Segmentation fault (11), possible coredump in /etc/apache2

It does not affect services running on Apache but it makes difficult to monitor state of services and also break my confidance that all is good with config.

As I have found with GDB   backtrace ("bt full") all those Segmentation fault (11) are result of clean_child_exit() which invokes during destroying of child process. That is why it does not affect our services.

Same time I want to avoid this problem.

I have attached config files and below is some explanations to those configs.

We are using wildcard SSL now - so using statements like
<VirtualHost   *:443 *:80>

in "ezserver.both"
with silent using of SSL certificates from default virtualhost "109.35.9.221_my.ezserver.com.ssl.conf".
Then with help mod_rewrite we force users to use HTTPS instead of HTTP.

Due changes in Apache 2.2.12 (I consider that is bug in Apache)
we using trick in ports_STAGING.conf
    Listen 443 http

More on that is here:

Same time "Segmentation fault" we was reciving before using wildcard certificates and using trick in "Listen" statement
