MySQL replication can break for a wide multitude of reasons. The following is a quick and dirty way to resume replication, if the error that appears in the output of SHOW SLAVE STATUS\G indicates that replication stopped at a specific record.

It is a dirty way, because immediately after using it the database on the slave becomes different from that on the master by one record. If you can live with that, the skip-one method can help you quickly put the slave back in track.

On the MySQL CLI:

mysql> STOP SLAVE;
mysql> SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
mysql> START SLAVE;
mysql> SHOW SLAVE STATUS\G

Hopefully your replication will resume after this, and the value of your Seconds_Behind_Master will quickly be depleted.
