      Description

      There is no problem when I execute "insert into d1.table1 ..." on A. But when I execute the "grant ...; flush privileges;" when there is a problem in the C and D, the occurrence of a loop execution "grant ...; flush privileges;".

      then modification my.cnf on C and D. Add the following
      _m1.replicate_wild_ignore_table=mysql.%
      m1.replicate_wild_ignore_table=information_schema.%
      m1.replicate_wild_ignore_table=performance_schema.%
      m2.replicate-ignore-db=d1_
      still loop execution,but just execute "flush privileges;".

      and the bin log like this:
