MySQL synchronization failure recovery due to the same server-id

MySQL synchronization in the slave database has been stopped,

Use show slave status \ G to view Slave_IO_Running: No. The server Load balancer instance fails to be started, and no error code is displayed. The following error is reported in the mysql error Log:

090216 21:06:10 [Note] Slave: deployed ed end packet from server, apparent master shutdown:

090216 21:06:10 [Note] Slave I/O thread: Failed reading log event, reconnecting to retry, log 'mysql-bin.0444 'position 77911

090216 21:06:11 [Note] Slave: connected to master 'rsync @ 10.10.10.10: 100', replication resumed in log 'mysql-bin.0444 'at position 3306

I used the previous method for a long time. I searched from the Internet for the same server-id, and then confirmed with another colleague that another slave database was originally configured, is a direct copy of my. cnf configuration file. After changing to a different server-id, restart the slave and the synchronization becomes normal.
