Confusing MySQL Replication Error Message

I already wrote about some MySQL Error Messages which are confusing, here is one more:

After setting up new slave Server I’m getting error log file flooded with messages like this and there is no hint in the message what would explain what is wrong.

In fact the issue in this case is (because of configuration error) two slave servers got the same server-id.

Seriously in this case Master clearly sees the problem in this case as there are 2 servers with same server-id connected and replicating so it should report it to the slave instead of sending end packet.

At very least it would be nice to include possible reason for this error message which MySQL already does in many other cases.

I’ve now filed it as a bug.
