Lost layout

Hey guys. I have a strange occurance and wondered if anyone has seen
it before. I have a standard layout set up with 3 layout files.
Everything works peachy for a while, and then the site (running in
production mode) “loses” or confuses it’s layouts. The admin area will
have the public layout or there will be no layout at all (eliminating
the nav menus).

This was never a problem in development or when I run the site
locally. This has happened twice in the last month. If I restart the
FastCGI processes, everything goes back to normal.

Anyone have any idea what might be going on? Could Rails be caching
the layout somehow? Thanks for any help.
