Title:
  creating multiple instances

Status in OpenStack Compute (Nova):
  Expired

Bug description:
  Running into dead lock errors when launching instances where instance count > than 5.
  Running Ice house on ubuntu 14.04
  Using Haproxy and maria DB cluster.
   
  If I run instance creation with instance count < 5 , everything works correctly.
  I suspect issue related to optimistic concurrency with mariaDB and nova not handling it correctly.
