I have the multi master set up with three servers, suddenly the slave thread stopped on the server because of the below error:
Slave I/O: The slave I/O thread stops because a fatal error is encountered when it tried to SET @master_binlog_checksum on master. Error: , Error_code: 1593
After changed the master_verify_checksum setting to on this sever, it works again, but the other 2 servers without this problem even the master_verify_checksum is still off.
How this happened?
