Error: Rewrite or internal redirection cycle after some time

[thiagotognoli]

Thanks for the reply, but do not know if this is the problem because the
open_file_cache is not configured at global level, and index.php is not
changed or replaced, this file was never changed because it is the default
magento, have any other ideas of what might be?

I appreciate the help ...
