XMS web Interface not available after yum update

Symptom:

Dialogic® PowerMedia™ Extended Media Server ("XMS") web console is not available after using yum to apply Linux OS updates. The error message varies according to which browser you are using and, as of December 2014, was as follows:

Chrome : This webpage is not available / The connection to [ip address] was interrupted. / Error code: ERR_CONNECTION_RESET
Internet Explorer : This page can’t be displayed
Firefox : Problem Loading Page / The connection was reset / The connection to the server was reset while the page was loading.

If the user checks the status of the httpd service, it's not running:

[root@xms2 ~]# service httpd status
httpd is stopped

If the user tries to start httpd manually, it fails as follows:

[root@xms2 ~]# service httpd restart
Starting httpd: [Wed Nov 26 11:48:25 2014] [warn] module ssl_module is already loaded, skipping
[Wed Nov 26 11:48:25 2014] [warn] _default_ VirtualHost overlap on port 443, the first has precedence
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:443
no listening sockets available, shutting down
Unable to open logs                                                           [FAILED]

Reason for the issue: 

When yum updates the package mod_ssl (an example of the full package name would be "mod_ssl-2.2.15-39.el6.centos.x86_64"), it creates a new /etc/httpd/conf.d/ssl.conf file, which interferes with PowerMedia XMS's usage of httpd.

Fix:

Run the following as root:

mv /etc/httpd/conf.d/ssl.conf /etc/httpd/conf.d/ssl.conf.orig
service httpd start

Which should output simply:

[root@xms2 ~]# service httpd start
Starting httpd: [ OK ]
