Redis error in flushdb


  Testing out running my suite on Ubuntu 14.04 (Trusty) and am seeing this error a lot (never saw it before on Ubuntu 12.04 (Precise)) - Anyone have any ideas what the culprit might be

  Failure/Error: REDIS.flushdb
    Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)
  # ./spec/rails_helper.rb:173:in `block (2 levels) in <top (required)>'
  # ------------------
  # --- Caused by: ---
  # IO::EINPROGRESSWaitWritable:
  #   Operation now in progress - connect(2) would block
  #   ./spec/rails_helper.rb:173:in `block (2 levels) in <top (required)>'


We are also seeing this intermittently. On some containers we cannot connect to Redis even though plenty of time has passed since the ‘Starting Redis’ step.
