Redirect loop with domain mapping subdirectories

We have moved our server to a vps at hostgator. I have a multisite network the main site is **URL REMOVED ON REQUEST**, the sub sites are

**URL REMOVED ON REQUEST** style
supposed to map to **URL REMOVED ON REQUEST**

**URL REMOVED ON REQUEST** spotlight
supposed to map to **URL REMOVED ON REQUEST**

**URL REMOVED ON REQUEST** /travel

supposed to map to **URL REMOVED ON REQUEST**

**URL REMOVED ON REQUEST** /faces

supposed to map to **URL REMOVED ON REQUEST**

When I turn on domain mapping I get a redirect loop.

The domains are added as parked domains at hostgator. The server setup is a vps.

Currently I would like to only work with faces and travel and I will add them and turn on domain mapping for them. I can't have style and spotlight go down.

Can you help me diagnose the redirect loop?
