        Position: 2006432
    Binlog_Do_DB: site3,site2

  • Replicate_Do_DB and similar options do not work exactly the way most people assume. You need BINLOG_FORMAT=ROW on the master if you want this configuration to be stable, or better, just replicate everything. Change that option in my.cnf on the master and restart it, then see what results you observe.

Reset to default
3 
USE site99;
INSERT INTO site2.mytable ...;

will not be replicated. This is because the USE controls replication, not the db.tbl syntax.

If this does not provide the answer, please provide an example of the code that fails, plus mysqldumpbinlog against both the Master's binlog and the Slave's relay_log. This should show whether or not the query made it that far.
