>From the logs it looks like the loop is caused by error_page you 
use, and recursive_error_pages set somewhere in your 
configuration.  As long as your error handler script times out 
(likely because it can't cope with load), nginx tries to call it 
again, then again, then again.  This continues till nginx reaches 
the redirections limit and logs the message about it.

Find where recursive_error_pages is set and switch it off - or, 
rather, just remove it from the configuration.  As previously 
said, the default is correct and should not be changed unless you 
understand what you are doing.  This should resolve your problem.
