Apache failure, also always goes down at 12AM eastern time

I get cpanel email alerts every now and then that httpd has failed and attempts were made to restart automagically, but doesn't work. When I SSH and try to manually restart apache, I notice the following errors: [Sun Jun 21 16:53:03 2009] [error] VirtualHost x.x.x.x:0 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results [Sun Jun 21 16:53:03 2009] [error] VirtualHost x.x.x.x:0 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results [Sun Jun 21 16:53:03 2009] [error] VirtualHost x.x.x.x:0 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results [Sun Jun 21 16:53:03 2009] [error] VirtualHost x.x.x.x:0 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results [Sun Jun 21 16:53:03 2009] [error] VirtualHost x.x.x.x:0 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results [Sun Jun 21 16:53:03 2009] [error] VirtualHost x.x.x.x:0 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results Furthermore at precisely 12:00 AM midnight, eastern time, apache will screw up and the site will be unable to connect to the database. It seems to fix itself ater 5 to 15 minutes. I need to have these sudden apache crashes stop -- please fix. The site is a wordpress site running on a CentOS server with PHP and Apache.
