How does the MySQL error message look like?

  SHOW SLAVE STATUS<br>G
      ...
      Last_IO_Errno: 1595, Relay log write failure: could not queue event from master

What does the MySQL error message mean?

MySQL had a problem with a binary log event and could not write it to the relay log.

When does this MySQL error message happen?

We tried to replicate from MySQL 5.0 to MariaDB 10.3. It seems like the MySQL 5.0 binary log format is too old for MariaDB 10.3.

How to fix this MySQL error?

We will try to use a MariaDB 5.5 intermediate Slave.
