Drupal 7, CiviCRM 4.6, I've just switched a site from being a directory of one domain to it's own new domain. After clearing all caches and resetting the backend configuration, it's able to load the dashboard, but other pages result in what I believe is a race condition - specifically, loading the page seems to trigger the server into calling itself for the same page (i.e. generating an outgoing request to the url being requested). So it ends up in quite the death spiral of resource use.
I know that 4.6 uses outgoing requests to itself to populate the dashboard, but that's not exactly the issue here. I also have noticed that 4.6 uses http requests to itself to identify it's own version, which is also a kind of crazy thing, and I wonder if that's what's creating the death spiral in this case.
Any clues or similar experiences?
