Issue/Introduction



After configuring SSL on our R12.52 SP1 SPS in order to configure a Federation partnership, we cannot start it anymore. 

When we check the server.log we do see the following errors happening during startup:

How can we solve this issue?

Environment

SPS R12.52 SP1

Resolution

This error occurs when two or more VirtualHosts contain the same hostname value. This can happen if you have enabled SSL and both httpd.conf and httpd-ssl.conf contains the same VirtualHost information too in the hostnames directive.

Changing the hostnames value in the VirtualHosts so they are not duplicated, and restarting SPS, will solve the issue.
