Failed to run multiple debezium MySQL Connectors to work with multitenant. i.e, when multiple source connectors connected to different databases with in the same database server in azure.

We tried to connect multiple debezium MySQL connectors with different database with in the same azure mysql  database server for different clients and it was running with two brokers on single node. For one connector it was working fine. Second source connector worked  for few minutes and returned the following errors.
