If an aux transaction fails at its lowest level, there is a builtin retry mechanism before erroring out. Currently an error message is printed after each failed attempt even though the aux transaction might succeed on retry. This change switches the alert level to warning on these attempts and makes sure an error message is printed if the transfer errors out after retries.
