      dual master with parallel replication memory leak in write master
      (slave_parallel_threads=8)

      if write in master(active) frequently, master(active) use memory more and more and then physical memory give out,2G physical memory per day,and then swap give up,the OS OOM Killer killed mysqld process.

      if you stop slave on master(active) before OOM Killer killed,the OS reclaim a lot of physical memory
