We ran into an issue upgrading to 8.0 this weekend. It appears that there was not enough memory in the JVM to run the database backup. As a fail safe, QB seems to attempt to reduce the number of rows in a query to attempt to load less into the JVM. However, It seems that even 1 row was too big, which put the backup into an infinite loop writing rows "(17->16)" over and over to a backup file. I would have expected the backup to fail once the end of the range was smaller than the start.
I will attach the relevant portion of the output logs.
