This message suggests there is a bug somewhere.  In particular, if 
you use 3rd party modules ("extras" suggests this may be the 
case), it may be a bug in a 3rd party module.  The message should 
contain additional information to help to identify the request 
triggered the bug.

Also, as you are using nginx-plus, you may want to contact 
technical support.
