Hi All,

I had a system replication on Linux consisting of MASTER and only one SLAVE.
I stopped replication, I did a backup on my slave and it recreated in
another machine so now I have two SLAVES connected to database MASTER.

But I found problems. I show you the output on my database MASTER and SLAVE
who is failed:

Any suggestion?
