the master_log_file and master_log_pos values keep changing automatically?
when that happens the replication doesn't work correct anymore!
mysql> change master to master_host='192........', master_user='replicate', master_log_file='mysql-bin.000021', master_log_pos=154;
so after i apply this and after few minutes the mastre_log_file and master_log_pos values change automatically then the replication doesn't work correct anymore.
