Hi, I am using MongoDB: 3.6.17 in my setup. since MongoDB version < 4.0 does not support change streams in database level. I am registering multiple connector instances on my setup. I have 10 connector instances listening to 10 collections in my setup. I try to load around 5000 documents in the collections. After some time I start seeing failures like. and the connector fails and the related Kafka topic does not only partial messages.

Also when I look into the connector status in curl -X GET http://localhost:8083/connectors/mongo-source-2/status the result says its running. but the connector is in a failed state.
