Description

Hi,

We have a Kafka Connect JDBC Source Connector which keeps polling for new records in a Oracle table every minute and push the new records to Kafka Topic. New records are determined by an incrementing column.

In general everything works well but once in a while we see that even though there were new records with incrementing column those records doesn't get pushed to the Topic. There is no clue of any error in the logs and the connector is in running state. Only after we restart the Connector the new records are pushed to the Topic. 

Any idea in what situation can this happen?. 

Rgds
