MySQL 5.6 slave stopped because of error SET @master_binlog_checksum

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?
