The problem is that these tests run optimistic parallel replication with non-transactional mysql.gtid_slave_pos table. Very occasionally InnoDB stats update may race with one another and cause a parallel replication deadlock kill after the mysql.gtid_slave_pos table has been updated. Since mysql.gtid_slave_pos is non-transactional, the update cannot be rolled back, and transaction retry will fail with a duplicate key error in mysql.gtid_slave_pos. Fixed by altering the storage engine to InnoDB for the table. Signed-off-by: Kristian Nielsen <knielsen@knielsen-hq.org>
