Apache 2.2.23 SSL error RE httpd.conf

I am using Apache 2.2.23 with PHP 5.4.10 on my OS X Server.

The Apache2 error_log contains the following error messages:

[Sat Jan 12 09:50:19 2013] [notice] caught SIGTERM, shutting down
[Sat Jan 12 09:50:23 2013] [notice] Apache/2.2.23 (Unix) DAV/2 PHP/5.4.10 mod_ssl/2.2.22 OpenSSL/0.9.8r configured — resuming normal operations

Could that be due to the entries in the httpd.conf shown at the bottom of this post? Does it matter? What does 'caught SIGTERM' mean?
Also, why does the error mention mod_ssl/2.2.22 (shouldn't that be mod_ssl/2.2.23)? Sorry for all the questions but I'm still learning.

I am not currently using SSL although I do want to get that working eventually.

The Apache2 httpd.conf file contains the following lines:

LoadModule ssl_module libexec/apache2/mod_ssl.so

'#' Secure (SSL/TLS) connections
'#' Include /private/etc/apache2/extra/httpd-ssl.conf

'#' Note: The following must must be present to support
'#' starting without SSL on platforms with no /dev/random equivalent
'#' but a statically compiled-in mod_ssl.

<IfModule ssl_module>
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
</IfModule>
